steps
1. Solve: x + 79 = 194
Solution: x + 79 = 194
x + 79 - 79 = 194 - 79
x = 115
You need to get
the variable by itself
(isolate the variable).
To undo adding 79,
subtract 79 from
both sides.
steps. 2. Solve: x - 56 = 604
Solution: x - 56 = 604
x - 56
+ 56 = 604 + 56
x = 660
You need to isolate the variable.
To undo
subtracting 56, add 56 to both sides.
Solution: x + 79 = 194
x + 79 - 79 = 194 - 79
x = 115
