Question

What value of x satisfies the system of equations {2x+5y=35x=−10−15y? Enter your answer as the correct value for x, like this: 42

Answer 1

Answer:

x = 23

Step-by-step explanation:

2x + 5y = 35 * (-3) ------>  -6x -15y = -105 (A)

x = -10 - 15y -----> x + 15y = -10 (B)

(A) + (B)

-5x = -115

x = 23
