Solve for z.

2z + 2 + 4z - 4z + 4z = 7

Z =

Z=0.8

Step-by-step explanation:

Combine the opposite terms

2z+2+4z=7

Add

2z and 4z

6z+2=7

Move all terms not containing z to the right side of the equation.

Subtract 2 from both sides of the equation.

6z=7-2

6z=5

Divide each term:

6z/6 = 5/6

Decimal Form:

z=0.8
