Question

4x-y=25, 5x+3y=16 solve by the substitution method or elimination method
​

Answer 1

Answer:

Step-by-step explanation:

4x-y=25   -1

5x+3y=16    -2

multiply eqn 1 with 3 to get 3 as coeffeicient with y variable.

12x - 3y = 75

5x + 3y = 16

now add,

17x = 91

x = 5.35

5(5.35) + 3y = 16

y = -3.58

Answer 2

Answer:

x = 91 / 17

y = - 61 / 17

Step-by-step explanation:

I have done this problem in both the methods.
