How to do this algebra problem -7(7×-3)=126

x = -2.14

Explanations:

How to do -7 (7x - 3) = 126

1. Use distribution property

-7(7x) - 7(-3) = 126

-7 times 7x = -49x

-7 times -3 = 21  (Negative times Negative sign = positive sign)

-49x + 21 = 126

2. Combine the like terms

21 and 126 are like terms

-49 = 126 - 21 ( When negative sign or positive sign crosses an equal sign, the negative sign changes to positive and positive changes to negative)

-49x = 105

3. Divide

Divide via by -49

-49x/-49 = 105/-49

x = -2.14

c. side angle side. u shares the same sides
