Solving simultaneous equations

Hello

How do you solve the following simultaneous equations? (can you please show me the steps on how to solve the following equations)

2y + x = 10 and x= 3 + 5y

Thank you

2. Rearrange the first equation to get $x=10-2y$ and now substitute that into the second equation for x to yield

$10-2y=3+5y$ now you have an equation of one variable which you should be able to solve

Once you get your answer for y, plug the value of y into either of the equations and solve for x

3. ## Rezolve

Thank you
2y+3+5y=10
7y=7
y=1

x=3+5x1
x=8

Very easy
