Answer:94.2 m
Step-by-step explanation:
The point would become (8,2)
3+5=8
4-2=2
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
It should be Expand by distributing terms.
