expand 3(x/3-10=-7)

expand

3 (\frac{x}{3} - 10 = - 7)

x - 30 = - 21

Solution steps

3 (\frac{x}{3} - 10 = - 7)

Distribute parentheses

= 3 \cdot \frac{x}{3} + 3 (- 10 =) + 3 (- 7)

Apply minus-plus rules

+ (- a) = - a

3 \cdot \frac{x}{3} - 3 \cdot 10 = - 3 \cdot 7

Simplify

3 \cdot \frac{x}{3} - 3 \cdot 10 = - 3 \cdot 7 : x - 30 = - 21

x - 30 = - 21

(sin (x) sin (y) - x e^{y}) d y

\frac{d}{d t} ((x) (t^{3} + t - 3))

\frac{1}{5} (1 + e^{2 x})

(x + 3) \cdot ln (x + 3)

(1 - c e^{- \frac{x ^{2}}{2}})^{2}
