Identify the mistake(s) in the work below:
3x + y - 25
-x-3
Step 1: One equation in nitrendy solved for the variable: y-3
Step 2: Substitution time: 3x + (x - 3) - 25
Step 3: Distribute: no need for this problem
Step 4: Combine like terms: 2x - 3-25
Step 5: Solve for the variable: 2x - 325
-3
- 3
2x22
2 2
X11
Step 6: Plug the answer from step 5 into one of the equations:
y=x-3
y = (11) – 3
y = 8
Solution/POI: (8, 11)
