Question

I’ve been having trouble with these all week!

Answer 1

Answer:

Step-by-step explanation:

so you will move constant to the right side and change the sign. 72x=223-7

then you will subtract the numbers 72x=223-7 and that will give you 72=216

then you will divide both sides by 72  and that will give you

1. x=3 .

Answer 2

Answer:

3

Step-by-step explanation:

1. subtract 7 on both sides since 7 and 223 do not have variables next to them

2. rewrite as 72x=216

3. divide by 72x on both sides

4. x=3
