Question

One number is 5 more than another number. If the sum of the number is 285 find the numbers.

Answer 1

one number is x

the other one is y=x+5 (Because is five more than the first one)

so the equation will be

x+y=285

x+(x+5)=285

First, we sum like terms

2x+5=285

then we isolate the x

2x=285-5

2x=280

x=280/2

x=140

therefore, one number is 140 and the other number is 145.

y=140+5=145

y=145
