Β (x, y) = (-3 5/8, 1 5/16)
Step-by-step explanation:
Add y+14 to the second equation to get ...
Β 3.5x +14 = y
Substitute this for y in the first equation:
Β 2.5x -3(3.5x +14) = -13
Β 2.5x -10.5x -42 = -13
Β -8x = 29
Β x = -29/8 = -3 5/8
Using this in the formula for y, we get ...
Β 3.5(-29/8) +14 = y
Β -203/16 +14 = y = 21/16 = 1 5/16
