How do I do this Algebra problem?

Question

1. 6.95x+19.95y=60.75

2x+4y=14

Answer 1

using substitution would be easiest since the first equation does not use whole number integer values. so just solve for x or y in the second equation (2x = 14 - 4y => x = 7 - 2y) and plug 7 - 2y into the x in the first equation. now it should be pretty simple to solve for y, and after doing so, just plug the y-value back into one of the equations to find the x. when you have numbers for both x and y, you can plug them into both equations to make sure they work in both to check your solutions.

Answer 2

its a substitution problem

2x+4y=14

2x=14 - 4y

x=7 - 2y    

now take the other equation and substitute the value of x

6.95(7 - 2y)+19.95y=60.75

48.65- 13.9y + 19.95=60.75

48.65 + 6.05y = 60.75

6.05y= 12.1

y=2

now take 2x+4y=14

as y=2

therefore 2x+4(2)=14

             2x+8=14

              2x=6

             x=3

Ans: y=2

        x=3
