Gerald and his dog Spike get on the scale together. Their combined weight is 128 pounds. If the ratio of Gerald's weight to Spike's weight is 3:1, how much does Gerald weigh?

96lbs

Step-by-step explanation:

g + s = 128

g = 3s

3s + s = 4s = 128

s = 128/4 = 32

g = 3s = 96

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
