Question

Solve the system by substitution.

y = x - 8

y = 2x - 14


The solution is (_, _).

Answer 1

x= 6

y= -2

Explanation:

y = x-8........equation 1

y= 2x-14.......equation 2

Substitute x-8 for y in equation 2

x-8= 2x-14

x-2x= -14+8

-x= -6

x= 6

Substitute 6 for x in equation 1

y= x-8

y= 6-8

y= -2

Hence x = 6 and y is -2
