Answer:
(2, - 6 )
Step-by-step explanation:
4x + 3y = - 10 → (1)
4x - y = 14 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the y- term
12x - 3y = 42 → (3)
Add (1) and (3) term by term to eliminate y
16x + 0 = 32
16x = 32 ( divide both sides by 16 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
4(2) + 3y = - 10
8 + 3y = - 10 ( subtract 8 from both sides )
3y = - 18 ( divide both sides by 3 )
y = - 6
solution is (2, - 6 )
