Question

Three students are working to find the solution set of this system of equations y=3x-4 2y=6x-8

Answer 1

x=1

Explanation:

To solve this equation, you must substitute. The equation for y is given. To use substitution, you have to put the y equation into the second one. In this case it would look something like this:

2(3x-4)=6x-8

(distribute)

6x-8=6x-8

(add 8)

6x=6x

(divide by 6)

x=x

In this circumstance, x is equal to 1.
