Answer:

(2, 3 )

Explanation:

- x + 3y = 7 → (1)

x - 4y = - 10 ( add 4y to both sides )

x = 4y - 10 → (2)

Substitute x = 4y - 10 into (1)

- (4y - 10) + 3y = 7 ← distribute parenthesis by - 1

- 4y + 10 + 3y = 7

- y + 10 = 7 ( subtract 10 from both sides )

- y = - 3 ( multiply both sides by - 1 )

y = 3

Substitute y = 3 into (2)

x = 4(3) - 10 = 12 - 10 = 2

solution is (2, 3 )
