Answer:
x = 3
y = 4/3
Step-by-step explanation:
2x − 3y = 2
x = 6y − 5
x - 6y = -5
2x - 3y = 2 | ×1 |
x - 6y = -5 | ×2 |
2x - 3y = 2
2x - 12y = -10
____________--
9y = 12
y = 12/9
y = 4/3
2x - 3y = 2
2x - 3(4/3) = 2
2x - 4 = 2
2x = 2 + 4
2x = 6
x = 6/2
x = 3
5x +y = 6
5x + 3y = -4
multiply top equation by -1 and bottom by 1
-5x -y = -6
5x+3y = -4
solve and get
2y = -10
y = -10/2
y = -5
answer is -5
