5=(2x+21)/3

5 = \frac{2 x + 21}{3}

x = - 3

Solution steps

5 = \frac{2 x + 21}{3}

Switch sides

\frac{2 x + 21}{3} = 5

Multiply both sides by

3

2 x + 21 = 15

Move

21

to the right side

2 x = - 6

Divide both sides by

2

x = - 3

2 x^{2} + 19 x + 9

(2 x^{3})^{2}

y^{2} = 100

x^{2} \cdot x

4 x + 9 + x + 7 + 5 x + 4 = 180
