Question

If (3x+y,5)=(4,x+1) find x and y

Answer 1

Answer:

The answer is $x=4,y=-8$

Step-by-step explanation:

We know that ordered pair $(a,b)$ and $(c,d)$ are equal, then $a=c$ and $b=d$

Thus  $(3x+y,5)=(4,x+1)$

          $\Rightarrow 3x+y=4$ and $5=x+1$

          $\Rightarrow y=4-3x$ and $x=5-1=4$

          $\Rightarrow y=4-3(4)$

                  $=4-12=-8$
