Question

5x=(2x-2)(m+6)
Solve for x

Answer 1

Explanation:

hello :

5x=(2x-2)(m+6) equivalent : 5x = 2xm+12x-2m-12

5x-2xm -12x=-2m-12

x(5-2m-12) = -2m-12

x(-7-2m) = -2m-12

x(2m+7) = 2m+12

if : 2m+7 ≠ 0 means m ≠ -7/2 so : x= (2m+12)/(2m+7)

if : 2m+7 = 0 means : m = -7/2 you have : x(0) = 2(-7/2)+12

0= 5 ( false) ... x no exist
