Question 1123762: So I was absent at school today so I missed an Algebra lesson. We are learning how we can solve word problems with one/two let statements. Let statements are very familiar to me but they left my mind as the new school year began. Here's my math problem. "The sum of twice a number and 4 is -22. Find the number." I can solve this no problem I just need the let statement(s). Thank you so much for your help if anyone responds!

The sum of twice a number and 4 is -22. Find the number.

let x equal the number.

this assigns the variable named x to represent the number that you want to find the value of.

your equation becomes -22 = 2x + 4, or 2x + 4 = -22

solve for x.

that's your number.

Let the number be n/x/p/q, or ANY VARIABLE of your choice.

Note that the variable can either be UPPER or LOWER case.
