Question

What are the values of x and y if you answer is not a whole number write it as a decimal and round if neccasasry

Answer 1

a) 3x + 5y = 26

b) 2x + 2y = 12

First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52

b) 6x + 6y = 36

Then take equation b) from the equation a) to eliminate the x component.

a) 6x + 10y = 52

- b) 6x + 6y = 36

0x + 4y = 16

y = 4 ?

Then substitute the value of y into either equation to find the value of x.

b) 2x + 2y = 12

2x + (2x4) =12

2x + 8 = 12

2x = 4

x = 2

I hope this new information i read helps you maybe understand it and as an example!
