Question

Solve each system of equations below. Write your solution in the form (x,y). Check your solution.

a) 3x - y = 14
x = 2y + 8

Answer 1

x = 2y+8

Explanation:

3x-y = 14

3(2y+8)-y = 14

6y+24-y = 14

5y = 14-24

y = -10/5

y = -2

now,

x = 2y +8

x = 2(-2)+8

x = 4

Therefore, the value of x is 4 and y is -2.
