Question

2x-5y+8=0,x-4y+7=0 solve x and y.

Answer 1

Hello dear...here is your answer

2x-5y+8=0

2x-5y=-8-----1

x-4y=-7--------2

multiplying by 2 in eq 2 and subtracting the equations

3y=6

y=2

put the value of y in eq 2

x-4×2=-7

x=1

hope it helps..plz mark as brainliest

Answer 2

Hey there !!
____________________________________

2x – 5y + 8 = 0 ...(1)
x – 4y + 7 = 0 ...(2)

From (2)
x = 4y – 7

Substituting x's value in (1)
2 ( 4y – 7 ) – 5y + 8 = 0
8y – 14 – 5y + 8 = 0
3y – 6 = 0
3y = 6
y = 6 / 3
y = 2

Putting y = 2 in (2)
x – 4 ( 2 ) + 7 = 0
x – 8 – 7 = 0
x – 1 = 0
x = 1

Thus, values of x and y are 1 and 2 respectively.
