-21y/4 = -5.25y
Yx7y = 7y2 (squared )
-56xy: it means -1 times 8 times x times 7 times y
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
-3
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
16+7y-8 = 7y+16-8 = 7y+8
X = Greatest, Y = Smallest 4X = 7Y + 11
a + 7y
343y3
-7y = -91 divide both sides by -7 y = 13
It is simply: 7y+46 or 7y-46
7y+3=y+18 Subtract three 7y=y+15 Subtract y 6y=15 Divide Y=15/6 That's your fraction if you need a decimal just type it in the calculator...
