5x+2y=22 - 2x+6y=3

Question

Round your answer to the nearest tenth

Answer 1

Greetings! Lets solve this shall we ?

So, we must find out what x and y are to the nearest tenth. Then, we multiply the first equation by -3 to cancel y first solving for x such that

-15x - 6y = -6

-2x + 6y = 3

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

-17x = -3

x = 3/17 = 0.2

Now we plug 3/17 into the first equation such that

5(3/17) + 2y = 2

15/17 + 2y = 2..............Subtract 15/17 to both sides such that

2y = 2 - 15/17............Common denominator is 17 so 2 - 15/17 = 19/17. Then

2y = 19/17.........Divide 2 such that

y = 19/17(1/2) = 19/34 = 0.6

I hope this helped!
