Adding, subtracting and finding the least common multipleStep by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
(15)*(2/3*x+10)-((15)*(x/5+36/5))=0
Step by step solution :
Step 1 :
36
Simplify ——
5
Equation at the end of step 1 :
2 x 36
(15•((—•x)+10))-(15•(—+——)) = 0
3 5 5
Step 2 :
x
Simplify —
5
Equation at the end of step 2 :
2 x 36
(15•((—•x)+10))-(15•(—+——)) = 0
3 5 5
Step 3 :
Adding fractions which have a common denominator :
3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x + 36 x + 36
—————— = ——————
5 5
Equation at the end of step 3 :
2 (x+36)
(15•((—•x)+10))-(15•——————) = 0
3 5
Step 4 :
Equation at the end of step 4 :
2
(15•((—•x)+10))-3•(x+36) = 0

Step 5 :
2
Simplify —
3
Equation at the end of step 5 :
2
(15 • ((— • x) + 10)) - 3 • (x + 36) = 0

Step 6 :
Rewriting the whole as an Equivalent Fraction :
6.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 3 as the denominator :
10 10 • 3
10 = —— = ——————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
6.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2x + 10 • 3 2x + 30
——————————— = ———————
3 3
Equation at the end of step 6 :
(2x + 30)
(15 • —————————) - 3 • (x + 36) = 0

Step 7 :
Step 8 :
Pulling out like terms :
8.1 Pull out like factors :
2x + 30 = 2 • (x + 15)
Equation at the end of step 8 :
10 • (x + 15) - 3 • (x + 36) = 0
Step 9 :
Step 10 :
Pulling out like terms :
10.1 Pull out like factors :
7x + 42 = 7 • (x + 6)
Equation at the end of step 10 :
7 • (x + 6) = 0
Step 11 :
Equations which are never true :
11.1 Solve : 7 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
11.2 Solve : x+6 = 0
Subtract 6 from both sides of the equation :
x = -6
One solution was found :
x = -6How did we do?
