Question

find the value of x and y in 2 x - 3 Y - 1= 0 and X + 2 Y - 4​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

2x - 3y - 1 = 0. (eq 1)

x + 2y - 4 = 0. (eq 2)


2x - 3y - 1 = 0
x + 2y - 4 = 0
(-) (-) (+)
x + y + 5
x=5 - y

Substitute x = 5 - y in eq 1 , we get

2 (5 - y ) - 3y - 1 = 0

10 - 2y - 3y - 1 = 0

10 - y - 1 = 0

9 - y = 0

y = -9

Place y = -9 in eq 2 , we get

x + 2 × (-9) - 4 = 0

x - 18 - 4 = 0

x - 22 = 0

x = 22

Hence , the value of x and y is

x = 22

y = -9
