Answer:
Step-by-step explanation:
3y = 2x - 9
2y = -3x + 4
3x + 2y = 4
-2x + 3y = -9
6x + 6y = 8
-6x + 9y = -27
15y = -15
y = -1
3(-1) = 2x - 9
-3 = 2x - 9
6 = 2x
3 = x
(3, -1)
Answer:
63 weeks
Step-by-step explanation:
252 - 3x = 378 - 5x
+ 5x +5x
Add 5x to both sides
252 + 2x = 378
-252 - 252
Subtract 252 from both sides
2x = 126
Divide 2 from both sides
x = 63
Check you work by plugging 63 where the x is
252 - 3(63)
252 - 189 = 63
378 - 5(63)
378- 315 = 63
