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
Rearrange the first equation to get $\displaystyle x=10-2y$ and now substitute that into the second equation for x to yield
$\displaystyle 10-2y=3+5y$ 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
2y+3+5y=10
7y=7
y=1
x=3+5x1
x=8
Very easy
