Solve the substitution 4x-3y=5
y=2x-3

4x - 3y = 5
y = 2x - 3

     4x - 3(2x - 3) = 5
4x - 3(2x) - 3(-3) = 5
        4x - 6x + 9 = 5
              -2x + 9 = 5
                     - 9  - 9
                    -2x = -4
                     -2     -2
                       x = 2
                       y = 2x - 3
                       y = 2(2) - 3
                       y = 4 - 3
                       y = 1
                 (x, y) = (2, 1)

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy
