Answer:
Step-by-step explanation:
A number increased by 7
<u>Step 1: Make an algebraic expression </u>
s + 7
<em>Sam has 7 baseball cards, and he gets 1 card every time he visits the store.</em>
x = - 1
Given
- 4(3x - 7) = 40 ( divide both sides by - 4 )
3x - 7 = - 10 ( add 7 to both sides )
3x = - 3 ( divide both sides by 3 )
