2.2z+3z=4.5-3.2

2.2 z + 3 z = 4.5 - 3.2

z = \frac{1}{4}

Decimal Notation

z = 0.25

Solution steps

2.2 z + 3 z = 4.5 - 3.2

Add similar elements:

2.2 z + 3 z = 5.2 z

5.2 z = 4.5 - 3.2

Subtract the numbers:

4.5 - 3.2 = 1.3

5.2 z = 1.3

Multiply both sides by

10

52 z = 13

Divide both sides by

52

z = \frac{1}{4}

x (x - 7) + 12 = x (x - 4)

- 9 y + 2 = - 8

x, 4 x + 8 y = 40

x, 4 x + 8 y = 32

4 x - 3 = 5 x - 8
