Question

Solve the system of equations.

A. (3,2)
B. (-2,0)
C. (0, -2)
D. (-4,2)

Answer 1

• Y = 1/2X + 4 ( Equation – 1)

• Y = –5/4X – 3 ( Equation – 2)

Here, Y = 1/2X + 4

Or, –5/4X – 3 = 1/2X + 4 (From equation 1 and 2)

Or, –5/4X = 1/2X + 4 + 3

Or, –5/4X = 1/2X + 7

Or, 1/2X + 7 = –5/4X

Or, 7 = –5/4 X – 1/2 X

Or, –5/4X – 2/4 X = 7

Or, –7/4 X = 7

Or, –7 X = 7 × 4

Or, –7X = 28

Or, X = 28/–7

Or, X = – 4

Here, in the fourth option, we can see that X= –4, Hence Option D— (-4,2) Is correct.

Answer 2

d. (-4,2)
