-7+((4x+2)/2)=8

- 7 + (\frac{4 x + 2}{2}) = 8

x = 7

Solution steps

- 7 + (\frac{4 x + 2}{2}) = 8

Move

7

to the right side

\frac{4 x + 2}{2} = 15

Multiply both sides by

2

4 x + 2 = 30

Move

2

to the right side

4 x = 28

Divide both sides by

4

x = 7

(\frac{5}{6})^{- 4}

x^{3} - 3 x^{2} - 18 x + 40

- 3 (x + 2) = 2 (x + 6) + 7

x^{4} - 1

x^{2} - 2 x + 5 = 0
