Question

Based on the lesson, which of the following would be the best approach for solving this system by substitution?

5x = y + 6
2x - 3y = 4

Answer 1

Solve the first equation for x.
Solve the first equation for y.
Solve the second equation for x.
Solve the second equation for y.

Answer 2

Do you have an idea of how to approach this question?

Answer 3

So it says we have to use SUBSTITUTION.
That means we have to solve for a variable in one of either equations; the question now is, which equation would be the easiest to work with and use in this case?

Answer 4

Here are our two equations:

5x = y + 6
2x - 3y = 4

As you can see, the first equation already has a variable set, y.
So you should solve for y in the first equation.

Answer 5

1.issolate the y
2.identify solution
3.substitute
4.solve for x
5.plug x in the equation
6. solve for y

Answer 6

But then again, it does say "Based on the lesson..." so i dont know how it is taught in your lesson.

Answer 7

id probably say solve for x on the second one

Answer 8

why so?
