Question

3x − 2y = 19 y = 2x − 14

Answer 1

Answer:

(9,4)

Step-by-step explanation

You can use substitution:

plug in y=2x-14 into 3x-2y=19

3x-2(2x-14)=19

then simplify it

3x-4x+28=19

-x+28=19

-x=-9

divide everything by -1

x=9

Then plug in x=9 into the equation to find y

y=2x-14

y=2(9)-14

y=18-14

y=4

To check your answer plug x and y back into the equation

3(9)-2(4)=19 check

4=2(9)-14 check
