-1+(4+4x)=83

- 1 + (4 + 4 x) = 83

x = 20

Solution steps

- 1 + (4 + 4 x) = 83

Remove parentheses:

(a) = a

- 1 + 4 + 4 x = 83

Add/Subtract the numbers:

- 1 + 4 = 3

4 x + 3 = 83

Move

3

to the right side

4 x = 80

Divide both sides by

4

x = 20

(\frac{- 10 - y}{2}) - 3 y = 2

s = \frac{1}{2} a^{2} v + c, v

x + 3 = 17

(x - 3)^{2} = (x + 5)^{2}

25 x + (- 11) = - 86
