7(-10 + 3x) = -49 Please explain aswell!

x=1

Step-by-step explanation:

To get the 7 away, we need to multiply it into the parentheses.

7*-10= -70

7*3=21

-70+21x= -49

Now we combine like terms and we move 70 over. Because we're moving it to the other side of the equation, it becomes positive.

21x= -49+70

-49+70 is the same as 70-49

70-49= 21

Now we put it together.

21x=21

To get the x by itself, we need to divide 21 on both sides.

21x/21= 21/21

21/21=1

x=1
