Question

How many solutions does the equation y + 12 = y + 10 + 2 have?
Zero One Two Infinitely many

Answer 1

y+12=y+10+2

y+12=y+10+2
y+12=(y)+(10+2)(Combine Like Terms)
y+12=y+12
y+12=y+12
S Subtract y from both sides.
y+12−y=y+12−y
12=12
Subtract 12 from both sides.
12−12=12−12
0=0
when we have a #=# (same number) it is infinte solutions

Answer 2

m=n <---no sol
m=m <--infinte
m=# <---one
