Answer:
x=-7,y=2
Step-by-step explanation:
3x - 4y = - 29
and 6x + 5y = - 32
3x - 4y = - 29 (1)
6x + 5y = -32 (2)
equation (1) x 2
6x-8y = -58
equation (2) × 1
6x + 5y = - 32
Substracting → - 13y = -26
13y = 26.
26/ 13 ⇒ y =
⇒ yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy = 2
Putting y = 2 in equation (1), we have
3x - 4(2) = - 20
→ 3x = -29 +8
→3x = -21
→ X = -7
x = - 7
