Solve the system of equations:\( \begin{cases} x + y = 7 \\ 2x - y = 1 \end{cases} \)
and we can substitute this into our equation for x to get what xis equal to.So,we have x=2-4(-1)=6.Now,to check our answer,we can substitute x =6 and y =-1 into both equations to makesure they equal the correct thing.2(6)+3(-1)=12-3=9 (6)+4(-1)=6-4=2These are...
Solving for two variables (normally denoted as "x" and "y") requires two sets of equations. Assuming you have two equations, the best way for solving for both variables is to use the substitution method, which involves solving for one variable as far as
