Question

Please Help ...

Solve using the addition method. What is the x-value of the solution to the system?

2x - 3y = -1
3x + 4y = 24

If you were to solve the system using the addition method, what would you multiply the first equation by in order to make the x's add out of this system?

-2x + 3y = 6
4x - 2y = 8

When solving the system by substitution, what would you plug into the second equation for the letter x?

x+2y=4
2x+2y=6

The ordered pair (4,2) is a solution to the system of inequalities below.

y>3x+2

Solve the following system of equations by graphing.

x + 2y = 4
2x + 4y = 8

What is the solution?

Solve the following system of equations by graphing.

x + 2y = 8
x + 2y = -4

What is the solution?

Answer 1

multiply the top one by 4, the bottom one by 3, then add and the y terms will go bye bye

Answer 2

For clarification, addition=elimination method...right?

Answer 3

you can also multiply first equation by -3
and second one by 2 :D :)

Answer 4

If so..

2x - 3y = -1
3x + 4y = 24

You would multiply the top by 4 and the bottom by 3 like satellite said.

8x-12y=-4
9x+12y=72

Answer 5

then when you add those up ^

the y is gone and you just solve for x

Answer 6

Solve for x how?

Answer 7

I'm so confused haha

Answer 8

8x-12y=-4
9x+12y=72

add them up^^
17x=68

Answer 9

to make x just x, divide by 17 ^

Answer 10

so therefore x=_____?

Answer 11

I got 4 ?(:

Answer 12

there you go :)

Answer 13

Thanks a bunch !(:
