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

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=

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
