Answer For Both Boxes Please class=

Sagot :

Answer:

(1,   )   is your answer

Step-by-step explanation:

x + 4y = 9

2x -4y = -6

add the two equations together

3x + 0y = 3

x = 1  :0

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

x + 4y = 9 → (1)

2x - 4y = - 6 → (2)

Adding (1) and (2) term by term will eliminate the y- term, that is

3x + 0 = 3

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

1 + 4y = 9 ( subtract 1 from both sides )

4y = 8 ( divide both sides by 4 )

y = 2

solution is (1, 2 )
