Question

If y - 12 = 23, what would you do to solve for x? *

option 1 - add the 12 to both sides

option 2 - subtract the 12 from both sides

option 3 - subtract 23

Answer 1

Option 1 - add the 12 to both sides.

Explanation:

If you meant solve for the variable, y, then you should:

Option 1 - add the 12 to both sides.

y - 12 = 23

Isolate the variable, y. Add 12 to both sides:

y - 12 (+12) = 23 (+12)

y = 23 + 12

Simplify:

y = 23 + 12

y = 35
