Question

Solve the system of equations: 3a + 4y = 33 y=X - 4 Fill in the coordinates of the ordered pair:( )

Answer 1

the given equations are

3x + 4y = 33 .......(1)

y = x - 4 ............(2)

multiply by 4 in equation (2)

4y = 4x - 16

now put the value of 4y in the equation (1).

3x + (4x-16) = 33

3x + 4x - 16 = 33
