Question

What is the x-value of the solution to the system of equations?

5x + 4y = 8

2x − 3y = 17

Answer 1

Answer:

X=75/23

Step-by-step explanation:

=> 3*(5X+4Y=8)+4*(2X-3Y=17)

=> (15X+12Y)+(8X-12Y) =24+51

=> 15X+8X=75

=> 23X=75

=> X=75/23

Answer 2

Answer:

x = 4

Step-by-step explanation:

5x + 4y = 8

2x − 3y = 17

(-4/3)*2x − (4/3)*3y = 17 *(4/3)

(8/3)x - 4y = 68/3

Combine equation  

5x + 4y = 8

(8/3)x - 4y = 68/3

-------------------------

(23/3)x = 92/3

x =  (92/3)/(23/3)

x = 4
