Question

Solve the system of linear equations below.


y = -2x + 19
y = x + 7

Answer 1

A. x = 4, y = 11 B. x = -12, y = -5 C. x = -4, y = 3 D. x = 8, y = 3

Answer 2

Since y = -2x + 19
and y = x + 7 ,
therefore , -2x+19=x+7
= -2x-x = 7-19
= -3x = -12
= x= -12/-3
= x = 4

Answer 3

Now solve for y by adding 7 to x.
