Step-by-step explanation:
Let's solve your equation step-by-step.
18=3-2x+4 (18-8)
Step 1: Simplify both sides of the equation.
18=3-2x+4 (18-8)
18=3+-2x+40
18 = (-2x) + (3+40) (Combine Like Terms)
18=-2x+43
18=-2x+43
Step 2: Flip the equation.
-2x+43=18
Step 3: Subtract 43 from both sides.
-2x+43-43=18-43
-2x=-25
Step 4: Divide both sides by - 2.
-2x

x = 12.5
Step-by-step explanation:
z = 3 - 2x + 4 (z - 8), z = 18
18 = 3 - 2x + 4 (18 - 8)
18 = 3 - 2x + 4*10
18 = 3 - 2x + 40
2x = 3+40 - 18
2x = 25
x = 12.5
