-4
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
7x+3-4x=4x-9-4x
3x+3=-9
Step 2: Subtract 3 from both sides.
3x+3-3=-9-3
3x=-12
Step 3: Divide both sides by 3.
3x / 3 = - 12 / 3
x=-4

x = - 4
Step-by-step explanation:
7x + 3 = 4x - 9
7x - 4x + 3 = 4x - 4x - 9
3x + 3 = - 9
3x + 3 - 3 = - 9 - 3
3x = - 12
x = - 4
