Question

How many solutions does the equation have?
4x+2(x-3)=8x+12
A. one solution
B.infinite solutions
C.no solution

Answer 1

a .one solutionthe solution is X= -9

Answer 2

4x + 2(x-3) = 8x + 12
⇒ 4x + 2x+ - 6 = 8x + 12
⇒ 6x - 6 = 8x + 12
⇒ 6x - 8x = 12 + 6
⇒ -2x = 18
⇒ x = 18/(-2)
⇒ x = -9

So it has one solution.
