f(x)=2x - 5

f(7 ) = 2(7)  - 5

f(7) = 14 - 5

f(7) = 9

Solve the system of equations using elimination.​
Eva8 [605]

Answer:

(69/40 , 7/11)

Step-by-step explanation:

multiply the bottom equation by 2

-4x + 8y = 12

4x+3y=-5

cancel out both 4x

8y+3y=11y

12+ -5 = 7

11y=7

divide both sides by 11

y=7/11

substitute that in for y

4x + 3(7/11) = -5

4x + 21/11 = -5

4x = -69/10

x= 69/40

Step-by-step explanation:

Use five and try the question over to make sure you calculated correct.
