Question

What is the value of x in the solution to the following system of equations?

x − 2y = 2
3x + y = 6

Answer 1

What method are you using? Substitution?

Answer 2

take y seperate from 2nd equation and put it into 1st u will have value of x

Answer 3

Okay, one second.

Answer 4

u can hv another method .. multiplying 2nd equation with 2 and than add the resultant equaton and 1st one .. u will have only x in answer

Answer 5

I don't really understand what you mean, can you show me the steps?

Answer 6

y= -3x + 6
Input it in.
x - 2(-3x + 6) = 2
x +6x - 12 = 2
7x = 14
x = 2

Then replug that back into one of the equations...

3(2) + y = 6
y + 6 = 6
y = 0

Answer 7

1. So first you isolate a variable in one of them.
2. Input that into the other equation.
3. Solve for a variable
4. Replace that variables value into either of equations
5. Solve for other variable
6. Finish.

Answer 8

oh, so you change the equation to equal y then use that to solve for x. thanks :)
