expand 7(3x+4y=-20)

expand

7 (3 x + 4 y = - 20)

21 x + 28 y = - 140

Solution steps

7 (3 x + 4 y = - 20)

= 7 (3 x + 4 = y - 20)

Distribute parentheses

7 \cdot 3 x + 7 \cdot 4 y = 7 (- 20)

Apply minus-plus rules

+ (- a) = - a

7 \cdot 3 x + 7 \cdot 4 y = - 7 \cdot 20

Simplify

7 \cdot 3 x + 7 \cdot 4 y = - 7 \cdot 20 : 21 x + 28 y = - 140

21 x + 28 y = - 140

x^{'} z (x) + y (x, z (x)) (x + z (x))

25 (33 - π)

\frac{( 2 + x ^{2} + 2 x ^{3} ) ^{2}}{4}

\frac{2}{3} (6 x - 15 = 18)

\frac{1}{2 ( - 28 - 16 a )}
