Question

Z= 3 - 2x + 4(z - 8) when z = 18

Answer 1

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 2

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
