(3x)/4 = 45/20

\frac{3 x}{4} = \frac{45}{20}

x = 3

Solution steps

\frac{3 x}{4} = \frac{45}{20}

Multiply both sides by

10

\frac{15 x}{2} = \frac{45}{2}

Multiply both sides by

2

15 x = 45

Divide both sides by

15

x = 3

(\frac{a ^{- 2} b ^{4} c ^{5}}{a ^{- 4} b ^{- 4} c ^{3}})^{2}

3 \leq x + 10 < 18

\frac{x}{8} \geq - 1.5

\frac{17}{15} \cdot \frac{2}{11}

(- \frac{x ^{5}}{2})^{4}
