Explain how to isolate the variable in the equation -2/3n + 7 = 15
vodka [1.7K]

Answer:

n = -12

Step-by-step explanation:

(-2/3)n + 7 = 15          

(-2/3)n+7-7 = 15-7               Subtract by 7 on both sides

(-2/3)n = 8                         Multiply by the reciprocal of the fraction, which is                                                                                                  

(-2/3)n*(-3/2) = 8(-3/2)      This makes it so you get n *1 and isolates n.

n = -24/2 = -12
