5(x+1)-2(x-2)=7

5 (x + 1) - 2 (x - 2) = 7

x = - \frac{2}{3}

Decimal Notation

x = - 0.66666 \dots

Solution steps

5 (x + 1) - 2 (x - 2) = 7

Expand

5 (x + 1) - 2 (x - 2) : 3 x + 9

3 x + 9 = 7

Move

9

to the right side

3 x = - 2

Divide both sides by

3

x = - \frac{2}{3}

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

7 x - 2.7 = - 6 x - 7.9

x, 6 y - x y^{2} = 1

\frac{x}{7} - 4 = 4
