Question

Can someone please show the steps for this and give the ordered pair? use the method of substitution to solve the system of linear equations.
2x-y=4
7x-3y=16

anonymous · Answer

Solve for y or x
Plug in that value of y or x into the other equation (in parenthesis)
The other equation has only 1 variable now, solve for it.
Put that result into the first equation to get y or x.

I'm new to all of this. Therefore I don't understand, and need to be shown step by step to solve completely.

campbell_st · Answer

take the 1st equation and make y the subject... 

can you do that..?

taepoohwae · Answer

use the method of substitution to solve the system of linear equations.
2x-y=4
7x-3y=16

campbell_st · Answer

so do you know how to make y the subject in the equation 

2x - y = 4

taepoohwae · Answer

As I mentioned this is my first algebra class so I know nothing. I need someone to solve this step by step.

campbell_st · Answer

ok... so add y to both sides of the equation 

2x = 4 + y

now subtract 4 from both sides

2x - 4 = y

now this can be substituted into the 2nd equation inplace of y

7x - 3(2x - 4) = 16

distributing

7x - 6x + 12 = 16

solve for x

when you have x substitute it into the 1st equation and solve for y

Thanks still not sure I really understand, but I'll study this more and use it as my notes.
