Question

what is the solution to the system of equations? y = x 3 x = –2

Answer 1

x= -2/3 y= -2/3, you solve for x so -2/3 3 goes under -2 then substitute into y=x this method is called substitution.

Answer 2

Answer: x=-2/3 and y=-2/3

Explanation: to solve this system of equations first we need to find the value of "x" using the second equation. After finding "x" we can know the value of "y" using the first equation. The procedure is shown as follows:

3x=-2

We can isolate the x by dividing all the equation by 3:

x=-2/3.

Now with the second equation:

y=x

y=-2/3
