2x+5y=10
5X-3y=20
Solve for x and y
Answers
Answer:
y = 5/3
x = 5
Step-by-step explanation:
EQUATIONS GIVEN,
2x+5y=10 (eq. 1)
5x-3y=20 (eq. 2)
SO,
IN EQUATION 2,
5x-3y=20
x = (20+3y)/5
NOW,
SUBSTITUTING IT INTO EQUATION 1,
WE GET,
2x+5y=10
2[(20+3y)/5] + 5y=10
(40+6y)/5 = 10
40+6y=10*5
40+6y = 50
6y = 50-40
6y = 10
y = 10/6
y = 5/3
SO,
x = (20+3y)/5
x = [20+3(5/3)]/5
x = 25/5
x = 5
SO,
y=5/3
x = 5
I HOPE YOU UNDERSTOOD THE QUESTION!!!
