Answer:
x=3
y=3
Step-by-step explanation:
x = 6-y
-plug in (6-y) into first equation
2(6-y)+3y = 15
12-2y+3y=15
-2y+3y = 3
y=3
x=6-3
x=3
double check:
(2*3) + (3*3) = 6 + 9 = 15
3 + 3 = 6
Answer:
x = 3
y = 3
Step-by-step explanation:
2x + 3y = 15
x + y = 6
2x + 3y = 15
x(-3) + y(-3) = 6(-3)
2x + 3y = 15
-3x - 3y = -18
Add:
2x + 3y = 15
-3x - 3y = -18
- x = -3
x = 3
Substitute x to any of the equation:
x + y = 6
3 + y = 6
y = 6 - 3
y = 3
