Answer:
(1, 0 )
Step-by-step explanation:
Given the 2 equations
4x - 3y = 4 → (1)
- 8x + y = - 8 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the term in x
8x - 6y = 8 → (3)
Add (2) and (3) term by term
(- 8x + 8x) + (y - 6y) = (- 8 + 8), that is
- 5y = 0 ⇒ y = 0
Substitute y = 0 into either of the 2 equations and solve for x
Substituting in (1)
4x - 3(0) = 4, that is
4x = 4 ( divide both sides by 4 )
x = 1
Solution is (1, 0 )
Answer:
x = 1 & y = 0
Step-by-step explanation:
4x - 3y = 4 -----(1)
-8x + y = -8 ------(2)
(1)×2 8x - 6y = 8 ------(3)
(3)+(2) 8x+(-8x)-6y+y = 8+(-8)
-5y = 0
y = 0
suby=0into(3) 8x - 6(0) = 8
8x = 8
x = 1
