Question

The sum of two integers is at most -57. One integer is 23. What is the other integer? Use x to represent the variable.

Answer 1

hint: "at most" means "less than or equal to" so

x + 23 <= -57

so solve for x

Answer 2

how i dont know how to do this im helping a friend and i just need an answer im not will im kylie

Answer 3

subtract 23 from both sides

Answer 4

x + 23 - 23 = ?

Answer 5

hint: the + 23 and the - 23 cancel each other out... so what would be left?

Answer 6

x

Answer 7

x=0

Answer 8

very nice!

so we have:

x <= -57 - 23

that means that x <= -80

so you can pick any integer that is -80 or less

i'm not sure why it asks for only one value of x though

Answer 9

**no, x is not equal to 0

Answer 10

omg i dont understand can you explain better

Answer 11

sure

let's go back to the beginning:

we have some unknown integer "x". we know that "the sum of the integer and 23 is equal OR less than -57"

that gives us:

x + 23 <= -57

Answer 12

now, we have "x + 23" on the left side. we want to "isolate" x. this means we want x by itself, so we must get rid of that 23 somehow.

the opposite of + 23 is - 23, so we can subtract to get:

x + 23 - 23 = x

Answer 13

however, since we subtracted 23 from the left side, we must also subtract 23 from the right side

- 57 - 23 = -80

so

x <= -80

this means that x must be an integer that is less than or equal to -80. so you can pick -80, or -81, or -82... etc.
