x+30=90+x/2

x + 30 = 90 + \frac{x}{2}

x = 120

Solution steps

x + 30 = 90 + \frac{x}{2}

Move

30

to the right side

x = \frac{x}{2} + 60

Multiply both sides by

2

2 x = x + 120

Move

x

to the left side

x = 120

3 (x + 1) - 2 (x - 1) = - (x + 5)

(x + 2)^{2} - (3 + x)^{2} = 1

- 2 (x - 5) + 6 = 4 - 6 (x + 5)

\frac{x}{2} = \frac{1}{2}

x, z = 9 x - y
