simplify 7(2x+7+9y)

Solution

simplify

7 (2 x + 7 + 9 y)

14 x + 49 + 63 y

Solution steps

7 (2 x + 7 + 9 y)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

7 (2 x + 7 + 9 y) = 7 \cdot 2 x + 7 \cdot 7 + 7 \cdot 9 y

= 7 \cdot 2 x + 7 \cdot 7 + 7 \cdot 9 y

Simplify

7 \cdot 2 x + 7 \cdot 7 + 7 \cdot 9 y : 14 x + 49 + 63 y

= 14 x + 49 + 63 y
