Answer:
x=19
Step-by-step explanation:
To find this we need to find the simplest form of y and x
Chart:
----------------------------------------------------------------------------------------------------------------Y | 45 |
X | 15 |
----------------------------------------------------------------------------------------------------------------
To find the simplest form divide both sides with their gcf which is right now 15 so divide by 15: For y 15 divided by 45 is 3, for x 15 divided by 15 is one so the graph looks like this:
----------------------------------------------------------------------------------------------------------------Y | 45 | 3 |
X | 15 | 1 |
----------------------------------------------------------------------------------------------------------------
So now we know this fact we can just divide 57 by 3
(We need to divide it to see how many times does it take for 3 to get to 57 and we can use that number to multiply it with 1 and only one since when y is 3 x is 1.)
57 divided by 3 is 19
So we multiply 19 with 1 which is 19
So x is 19
Graph:
----------------------------------------------------------------------------------------------------------------Y | 45 | 3 | 57 |
X | 15 | 1 | 19 |
----------------------------------------------------------------------------------------------------------------

Should be 10, or 9.65606. Hope this helps!
In a step by step fashion you solve the problem like so:
Move terms:
3f+2=8-3f
Combine like terms:
3f+3f=8-2
Divide
6f=6
Solution
f=1
You bring the numerals on to the other side of the equation, therefore dividing 19 by 3 and 6.
3x + 6y = 19
3x + y = 19/6
x + y = 3.17/3
x + y = 1.1
