Question

Is the ordered pair (0,5) a solution of the system of linear equations:

Answer 1

Recall that an ordered pair is a solution of a system of linear equations if it satisfies each equation.

Notice that:

`0+5=5.`

Also, notice that:

`-5\cdot0+2\cdot5=0+10=10.`

Therefore the ordered pair (0,5) satisfies the given system of equations.

Answer: Yes.
