Answer:
The solution to the system of equations is:
x = 6
y = -2
Step-by-step explanation:
Given the pair of equations:
3x + 4y = 10 .......................................................................(1)
-3x - 6y = -6 ......................................................................(2)
Add equation (1) and (2) to eliminate x
4y - 6y = 10 - 6
-2y = 4
y = 4/(-2)
= -2
Multiple (1) by 6, and (2) by 4 to eliminate y
(1) * 6:
18x + 24y = 60
-12x - 24y = -24
Adding:
18x - 12x = 60 - 24
6x = 36
x = 36/6 = 6
