Answer:
No
Step-by-step explanation:
For a point to be a solution of a system of equations, it has to work for both equations in said system. For this particular point, it doesn't fit into both.
12=5(2)+2
12=10+2
12=12
4(2)-12=0
8-12=0
-4=0
The second equation doesn't work out.
P = 3
Step-by-step explanation:
Multiply both sides by 3
48-9p=2p+15
Add 9p to both sides
48=2p+15+9p48=2p+15+9p
Simplify 2p+15+9p2p+15+9p to 11p+15
48=11p+15
Subtract 15 from both sides
48−15=11p
Simplify 48-15 to 33
33=11p
Divide both sides by 11
\frac{33}11=p11/33=p
Simplify 11/33 to 3
3=p
Switch sides
p=3
Kono Dio Da!!!
