Question

Match each equation on the left with its simplified version from the choices on the right. Do not solve. (not all the choices will be used.) -2(3x-10)=15 __ A. -6x+2=15 ⅕(30x-10)=15 __ B. 6x-2 = 15 3(2x-10)=15 __ C. 6x+2=15 -⅕(30x-10)=15 __ D. 6x-30 = 15 E. -6x+20=15 F. -6x-20 = 15

Answer 1

E. -6x + 20 = 15

Explanation:

Given the expression -2(3x-10)=15, we are to find the equivalent expression;

Open the parenthesis using the distributive law;

-2(3x-10)=15

-2(3x) -2 (-10) = 15

-6x + 20 = 15

Hence the simplified version of the expression is -6x + 20 = 15
