Sagot :
Answer:
you have to subtract 3y and then you do the same on the other side, then you end up with two numbers where you divide them and that will be your result
Step-by-step explanation:
Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 14 → (1)
3x + 3y = 15 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate the x- term
- 3x - 12y = - 42 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 - 9y = - 27
- 9y = - 27 ( divide both sides by - 9 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(3) = 14
x + 12 = 14 ( subtract 12 from both sides )
x = 2
solution is (2, 3 )
