Answer:
25/2
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

Answer:
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
