Answer:
<h2>
(-2, -3)</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Consider the following pair of equations:
y = 3x + 3
... 1
y = x − 1
... 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form
.
From both equations, we will substitute y = 3x+3 in equation 1 into 2 to have;
3x+3 = x-1
collecting the like terms;
3x-x = -1-3
2x = -4
Dividing both sides by 2 will give;
2x/2 = -4/2
x = -2
Substituting x = -2 into equation 1;
y = 3x+3
y = 3(-2)+3
y = -6+3
y = -3
The solution in (x, y) form is (-2, -3)
