3x + 7

Subtract 7 from both sides
Divide 3 to both sides
Cancel out the 3 from the left

Lets do this step by step :)
1st.
Subtract 7 from both sides.
3x +7 > -2
- 7 > -7 Now it cancels out on the left hand side. And we solve -2 - 7 = - 9
2nd.
Now lets set up our equation again.
3x > -9
3rd.
Now lets divide both sides by 3 to isolate x to be alone.
3x > -9
÷3 > ÷3 Now it cancels out on the left hand side. And we solve -9 ÷ 3 = -3
So our final answer is
x > -3
or in word form (x is greater than -3)
- have a lovely day :)
