15=2x+(10-3^2)

15 = 2 x + (10 - 3^{2})

x = 7

Solution steps

15 = 2 x + (10 - 3^{2})

Switch sides

2 x + (10 - 3^{2}) = 15

Remove parentheses:

(a) = a

2 x + 10 - 3^{2} = 15

3^{2} = 9

2 x + 10 - 9 = 15

Add/Subtract the numbers:

10 - 9 = 1

2 x + 1 = 15

Move

1

to the right side

2 x = 14

Divide both sides by

2

x = 7

5 x - 3 = - x - 9

x, 6 x - 5 y = 15

\frac{x}{3} + \frac{x}{2} = x - 1

6 z + 12 z - 18 - 5 z = - 12 z + 4 z - 11 + z

- 5 + 7 k = - 19
