x+2x+6=87
Step-by-step explanation:
let x represent the first number. 2x+6 would represent the second number since it's 6 more than (which would be addition) twice the first number (so you'd multiply the first number (which is represented by x) by 2. then, you'd set up the equation to be equal to 87.
so, the equation would be:
x+2x+6=87
