Answer:
x=1, y=1
Step-by-step explanation:
To solve the equations, we first have to label them.
4x +6y= 10 -----(1)
-10x +2y= -8 -----(2)
From (1): 2x +3y= 5 -----(3)
From (2):
-5x +y= -4
y= 5x -4 -----(4)
Subst. (4) into (3):
2x +3(5x -4)= 5
2x +15x -12= 5 (expand)
17x= 12 +5 (simplify, +12 on both sides)
17x= 17 (simplify)
x= 17 ÷17
x= 1
subst. x=1 into (4):
y= 5(1) -4
y= 5 -4
y= 1
