Question

Explain how to isolate the variable in the equation -2/3+7=15

Answer 1

n= -12

Explanation:

- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing

-7 = -7 n to the right

- 2n/3 = 8 multiply both sides of equation by - 3/2

-3/2 x (-2n/3) = -3/2 x 8

n= -3/2 x 8 cancel the common factor of 3

n= -12
