Question

Could i get some help with this problem. 7(x-3)=49

Answer 1

7x-21=49, 49-21= 28/7= x= 4

Answer 2

x = 10

Explanation:

- The first thing to do is open parentheses:

7 (x - 3) = 49

7x - 21 = 49

- Then add 21 to each side:

7x - 21 = 49

7x = 70

- Now divide each side by 7:

7x = 70

x = 10
