# Question #01a0e

In order to check if an ordered pair is a solution to a particular set of equations, you have to plug each number in (the ordered pairs take the format of $\left(X , Y\right)$) and see if the equations are still valid.
For the first problem: The ordered pair is $\left(4 , 3\right)$, meaning that $X = 4 \mathmr{and} Y = 3$. Plug these values in to get $2 \left(4\right) + 5 \left(3\right) = 25 , 8 + 15 = 25 , 23 \ne 25$, thus, the ordered pair is not a solution. Follow this same set of steps for the other two equations.
