Given
x = 3y + 3
x − 10y = −25
Substitute x into the second equation:
(3y + 3) − 10y = −25
3y + 3 − 10y = −25
−7y + 3 = −25
−7y = −28
y = 4
Now find x:
x = 3(4) + 3 = 12 + 3 = 15
Solution: (x, y) = (15, 4).
x = 3y + 3
x − 10y = −25
Substitute x into the second equation:
(3y + 3) − 10y = −25
3y + 3 − 10y = −25
−7y + 3 = −25
−7y = −28
y = 4
Now find x:
x = 3(4) + 3 = 12 + 3 = 15
Solution: (x, y) = (15, 4).
