Question

5 x + 4 Y is equal to 5 and 5 x + 3 Y equal to 10 ​

Answer 1

Answer:

5x+4y= 5

5x+3y=10

subtracting both equations:

y = -5

Therefore,

5x+ 4y = 5

5x + 4× -5 = 5

5x-20 = 5

5x = 5+20

5x = 25

x = 25/5

x = 5

Answer 2

Answer:

5× + 4y = 5

5× + 3y = 10

- - -

Step-by-step explanation:

5x + 4y = 5

5x + 3y = 10

- - -

_________

y = -5

5x + 4 × 5 = -5

5x + 20 = -5

5x = -5 - 20

5x = 25

x = 25 / 5

x = 5
