Question

2x+y = 11 and 7x-4y=-14. using substitution method​

Answer 1

Answer:2x + y = 11 → y = 11 - 2x (1)

7x-4y = -14 (2)

Substituring (1) into (2), we have

7x - 4(11 - 2x) = -14 simplify

7x - 44 + 8x = -14

15x - 44 = - 14 add 44 to both sides

15x = 30 divide both sides by 15

x = 2 and using (1) to find y, we have y = 11 - 2(2) = 11 - 4 = 7
