Answer:
x=2.5
y= -7
Step-by-step explanation:
1.)make y the subject of any equation
4x-y=17
-y=17 -4x
y = -17 + 4x
2.)substitute it in the next equation
-2x + 3(-17 + 4x)= -26
-2x -51 + 12x = -26
-2x + 12x - 51= -26
10x -51= -26
10x = 25
x = 2.5
3.) substitute the x- value into any equation
4x -y = 17
4(2.5)- y = 17
10 - y =17
-y = 7
y = -7
