Question

PLEASEEEEEEEEE HELP ME ON THIS ONE :D
What is the value of the x variable in the solution to the following system of equations?

3x + y = 6
6x + 2y = 8

A.) 0

B.) 4

C.) x can be any number as there are infinitely many solutions to the system.

D.) There is no x value as there is no solution to the system.

Answer 1

Same principle as the last one you posted. Substitute. This time substitute Y.

Answer 2

Take one of the equations and set it so that you have y on one side by itself and everything else on the other side of the equal sign.

HINT: Y = 6 -3x

Start with that

Answer 3

Tell me what you get :]

Answer 4

Ahh this is a tricky one, you might end up with just numbers on both sides. Do you remember from class what this means?

HINT: Your answer won't be a number.

Answer 5

Is the answer 'C'? ........

Answer 6

Hmmm. I don't think that is quite the right answer. I would go with D. No solution.

Answer 7

Oh, okay. Thank you! (: Its much appreciated.

Answer 8

Try graphing the two equations. Put them in Slope-intercept form.

Answer 9

What you are basically solving for is the point at which the two lines intersect on a graph. That would be your unknown variable.
