Answer:

The solution of the system is

x=8, y=11

Step-by-step explanation:

we have

$y = 2x-5$ ----> equation A

$y = x+3$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The intersection point is (8,11)

see the attached figure

therefore

The solution of the system is

x=8, y=11

4 (2x – 3)= 2( 3x + 1)
(4 (2x – 3)= 2( 3x + 1)) ÷ 2
2 (2x – 3) = (3x + 1)
4x - 6 = 3x +1
-3x -3x
__________
x - 6 = 1
+6 +6
______
x = 7
