Answer: 42 hope this helps and is right
Answer:
d = (2z + 3)/(p) - z
9514 1404 393
p = -9 5/9
Step-by-step explanation:
Undo what is done to p.
Multiply by 2.
p +10 = 4/9
Subtract 10.
p = 4/9 -10
2(5+y)+2y=38 10+2y+2y=38 4y=28 y=7 i think
Infinitely many solutions
x+y=3
2x+2y=6
x=3-y
2(3-y)+2y=6
6-2y+2y=6
6+0=6
6=6
infinitely many solutions
