Question

5x + 3y = 35
2x – 4y = 28​

Answer 1

Answer:

let y be 5

so let us put 5 in the place of y

Step-by-step explanation:

: 5x + 3(5) = 35

2x + 4(5) = 28

: 5x + 15 = 35

2x + 20 = 28

: 5x = 35-15

2x = 28-20

: 5x = 20

2x= 8

: x = 20/5

x= 8/2

: hence x = 4

(and you can even take x=4 and check your answer) :-)

Answer 2

Answer:

x = 112/13 and y = -35/13 these are the values of this equation
