Question

What is the solution to the system of equations?

Answer 1

( 5, - 2 )

Explanation:

3x - 2y = 19 -----> equation 1.

y = x - 7 -----> equation 2.

Substitute equation 2 in 1,

3x - 2 ( x - 7 ) = 19

3x - 2x + 14 = 19

x + 14 = 19

x = 19 - 14

x = 5

Substitute the value of x in equation 2,

y = 5 - 7 = - 2

( x, y ) = ( 5, - 2 )
