Consider the following pair of equations
y=3x +3
y=x - 1

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in(x, y) form

(-2 -3)

Step-by-step explanation:

                                                                    (1)           y = 3x + 3

                                                                    (2)          y =   x  - 1

Substitute the value of y from (1) into (2)         3x + 3 =   x  -  1

Subtract 3 from each side of the equation     3x       =   x  -  4

Subtract x from each side of the equation     2x       =         -4

Divide each side of the equation by 2       (3)   x       =         -2

Substitute the value of x from (3) into (2)                y = -2 - 1

Combine like terms                                                 y = -3

The ordered pair that satisfies the equations is (-2, -3).

In the Figure, the red line is the graph of Equation (1), and the blue line is the graph of Equation (2). The point of intersection is at (-2, -3).
