Which value of x satisfies both 3x + y = 9 and 3x − 5y = 15?

2 answers:

8 0

*Hint: In order to find the value of x you could solve this equation by the elimination method and eliminate y.

(3x + y = 9)5
3x - 5y = 15

15x + 5y = 45
3x - 5y = 15

18x = 60
x = 10/3

The answer would be A.

What’s the solution of x+y=29 and y=4x-11

tia_tia [17]

Answer:

x = 8

y = 21

Step-by-step explanation:

y = 4x − 11

x + y = 29

Solve for x:

x + y = 29

x + 4x − 11 = 29

5x − 11 = 29

5x = 40

x = 8

Solve for y:

y = 4x − 11

y = 4 × 8 − 11

y = 21
