Question

5x=3y = 11 4x-y =2 elimination

Answer 1

Step-by-step explanation:

5x - 3y = 11. -----(1)

4x - y = 2--------(2)

4x = 2 + y

x = 2 + y / 4 ------------------(3)

5x - 3y = 11

5(2+y/4) -3y = 11

10 + 5y / 4 -3y =11

10 + 5y - 4(3y) = 4(11)

10 + 5y - 12y = 44

-7y = 44-10

-7y = 34

y = -34/7

x = 2+y /4

x = 2+(-34/7) / 4

x = 2-34 / 4×7

x = 2-34/28

x = -32/28

x = -8/7

hope this helps you
