I trust that you meant to type
3h – 10 = 35.
If so, see work below.
1. Add 10 to both sides.
3h – 10 + 10 = 35 + 10
3h + 0 = 45
3h = 45
2. Divide both sides of the linear equation by 3 to find h.
3h/3 = 45/3
h = 15
Is h = 15 correct?
Prove:
Let h = 15 in the given equation.
If we get the same answer on both sides of the equation, then we will know that h = 15 is the right answer.
3(15) – 10 = 35
45 - 10 = 35
35 = 35
The fact that 35 = 35 means that our answer for h is 15.
