Need The Answers For The 2 Boxes class=

Sagot :

Answer:

(2, 2 )

Step-by-step explanation:

Given the 2 equations

3x + 6y = 18 → (1)

- 3x + 4y = 2 → (2)

Adding the 2 equations term by term will eliminate the x- term, that is

0 + 10y = 20

10y = 20 ( divide both sides by 10 )

y = 2

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

Substituting into (1)

3x + 6(2) = 18

3x + 12 = 18 ( subtract 12 from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

solution is (2, 2 )
