what is the step by step instructions to answer 7(1x-3)=7

Question

my kids have an homework assignments nd asking me for help

Answer 1

Shalayah, first we distribute the 7...

 

7(1x - 3) = 7

7(1x) + 7(-3) = 7

7x - 21 = 7

 

We need the x by itself on one side, so first we need to move the -21 to the other side by aadding (the opposite operation).

 

7x - 21 + 21 = 7 + 21

7x = 28

 

7x is 7 times x, and the opposite of multiplication is division.

 

7x/7 = 28/7

x = 4

 

Hope this helps!
