Question

Solve the system of equations algebraically.

*If necessary, write your answers as fractions in simplest form.

y = x + 2
y = -3x

Answer 1

Explanation:

y = x + 2 -------------(i)

y = -3x ----------------(ii)

substitute y = -3x i equation (i)

-3x = x + 2

-3x -x = 2

-4x = 2

x = 2/-4

x = -1/2

Substitute x = -1/2 in (ii)

y = -3 * -1/2

y = 3/2
