Answer:
Step-by-step explanation:
Open the brackets
3 x 2x = 6x
3x -3 = -9
4 x 2x= 8x
4 x 4= 16
6x - 9 = 8x + 16
Move same to same side
-16 -9 = 8x - 6x
-25 = 2x
x -25/2
x = -12.5
Answer:
x = -25/2 or -12.5
Step-by-step explanation:
3*(2x - 3) = 4*(2x + 4)
6x - 9 = 8x + 16
6x - 8x = 16 + 9
-2x = 25
x = -25/2 or -12.5
------------------------
check
3 * (2 * (-12.5) - 3) = 4 * (2 * (-12.5) + 4)
3 * (25 - 3) = 4 * (12.5 + 4)
3 * 22 = 4 * 16.5
66 = 66
the answer is good
