The left and right page numbers of an open book are two consecutive integers whose sum is 347. Find these page numbers.
azamat

Let the first page = x

The second page would be x + 1

Add them together to equal 347

X + x + 1 = 347

Combine like terms:

2x + 1 = 347

Subtract 1 from both sides

2x = 346

Divide both sides by 2:

X = 173

The smaller page number is 173

The larger page number is 174

One number is 18 more than three times another number. The difference in the numbers is 54. Find the numbers
Kruka [31]
The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
