198-22y = 220 -22y = 220-198 -22y = 22 y = 22/-22 y = -1
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
yes
maybe
2y + 3 = 42y = 4 - 32y = 1divide both sides of the equation by 22y/2 = 1/2y = 1/2 in fractionory = 0.50 in decimal
198-22y = 220 -22y = 220-198 -22y = 22 y = 22/-22 y = -1
Log4 64=y 64=4y 26=22y Therefore y=3
