Question

Arlo bought a salad for $8 and 3 hamburgers. His total was
$29. How much did each burger cost?

Answer 1

7 dollars :)
8 + 3x = 29
x = cost of burger
move the eight to the other side by subtracting it
3x = 21
divide by 3 to leave the x by itself
x = 7

Answer 2

Each hamburger cost 7 dollars.
