Question

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

Answer 1

Answer:

(-2, -3)

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)
