Help me with this!!!!!!!!!! please!!!!!!!!!!!!!

Answer 1

Answer:

(2, 3)

Step-by-step explanation:

3x + 4y = 18

-1 (-2x + 4y) = (8)-1

2x - 4y = -8

Elimination:                                  Side work:

 3x + 4y = 18                                  3x + 2x = 5x

 2x - 4y = -8                                   4y - 4y = nothing

   5x       = 10                                   18 - 8 = 10

    x = 2                                            Divide by 5 on both sides

Substitute back in to one of the equations

x = 2

3x + 4y = 18

3(2) + 4y = 18

6 + 4y = 18

4y = 18 - 6              Subtract 6 on both sides

4y = 12                  Divide by 4 on both sides

y = 3
