Question

What is the solution to the equation?

98 + g = 150
98 + g = 150. 98 + 98 + g = 150 minus 98. t = 52.
98 + g = 150. 98 minus 98 + g = 150 minus 98. t = 52.
98 + g = 150. 98 + 98 + g = 150 + 98. t = 52.
98 + g = 150. 98 minus 98 + g = 150 + 98. t = 148.

Answer 1

Solve 98 + g = 150 for g.

Subtract 98 from both sides:
g = 150 − 98
g = 52

Check: 98 + 52 = 150.

Notes on the lines you wrote:
- You must do the same operation to both sides. Adding 98 to the left but subtracting 98 on the right is inconsistent.
- The variable t appears but the equation uses g; the solution is g = 52.
