Answer:
- 2x +3(8 -3x) = 3
- x = 3
- y = -1
Step-by-step explanation:
The second equation tells you ...
y = 8 -3x
Using this expression in the first equation gives you ...
2x +3(8 -3x) = 3
2x +24 -9x = 3 . . . . . eliminate parentheses
21 = 7x . . . . . . . . . . . add 7x -3
3 = x . . . . . . . . . . . . . . divide by 7
y = 8 -3×3 = -1 . . . . . . use the second equation to find y
The solution is (x, y) = (3, -1).
