Use the elimination method to solve each system of equations,

11. 3x + 4y - 38

5x - 4y - 10

a. (5.6)

b. (6,4)

c. (6,5)

x=6 y=5

c. (6,5)

Step-by-step explanation:

just add the two equations together and the 4ys cancel out

3x+4y-38

5x-4y-10

8x-48

+48

8x=48

divide by 8

x=6

then add 6 in as x to the an equation

5 (6) - 4y-10

30-4y-10

20-4y

20=4y

divide by 4

y=5
