Question

find four solution of equation 2x + Y is equal to X + 3 Y + 4​

Answer 1

Answer:

2x - y = 4

Or, y = 2x - 4 …………equation (1)

Putting x = 0 in equation (1),

y = (2 x 0) - 4 = 0 - 4 = -4

Putting x = 1 in equation (1),

y = (2 x 1) - 4 = 2 - 4 = -2

Putting x = 2 in equation (1),

y = (2 x 2) - 4 = 4 - 4 = 0

Putting x = 3 in equation (1),

y = (2 x 3) - 4 = 6 - 4 = 2

Hence, four solutions of equation 2x - y = 4 are (0, -4), (1, -2), (2, 0), (3, 2).
