Question

Solve for x. State any restrictions on the variables.

a(bx+2)=cx-12;

A. x=(-12-2a)/(ab-c);ab≠c
B. x=(-12+2a)/(c+ab);ab≠c
C. x=(2a+12)/(c-ab);no restrictions
D. x=(ab-c)/(-12-2a);a≠-1

Answer 1

a(bx+2)=cx-12
abx+2a=cx-12
abx+2a-cx=-12
abx-cx=-12-2a
x(ab-c)=-12-2a
x= (-12-2a) / (ab-c)

Answer 2

ab can't equal c
