Question

Solve the following system of equations
x-2y=6 and y=11-3x

Answer 1

(x,y)

1. (10,4)

2. (3,22)

Explanation:

If you substitute 10 for the x and 4 for the y in the first problem, it becomes true.

x-2y=6 ---> 10- 2(2)=6

2 times 2 is 4 and 10 minus 4 equals 6.

Same rules apply to the second problem.

Answer 2

m=1/2 this is the 1st question.

m= -3 is the second question.

Explanation:

Use the slope-intercept form.
