\frac{3 x}{5} + 3 = 7

x = \frac{20}{3}

Decimal Notation

x = 6.66666 \dots

Solution steps

\frac{3 x}{5} + 3 = 7

Move

3

to the right side

\frac{3 x}{5} = 4

Multiply both sides by

5

3 x = 20

Divide both sides by

x = \frac{20}{3}

(x + 4)^{2} + 10 (x + 4) + 16 = 0

- 5 (1 - 5 x) + 5 (- 8 x - 2) = - 4 x - 8 x

\frac{2 x}{3} \cdot \frac{y}{5}

- x^{2} + 4 x + 21 \geq 0
