First, it'll help you to understand what "answer" means. The "answer" is the number
that 'x' must be in order to make your equation a true statement. There's only one
number that can do that.
Here's an easy way to find it:
x + 29 = 87
What do you have to do to the left side to get 'x' all alone ?
Whatever it is, do the same thing to each side.
Subtract 29 from each side:
x = 87 - 29
x = 58
348
What operation does 74 plus 13 equals 87 and 87-13 equals 74 demonstrate?
29 x 3 = 87
29
it equals 406
348
9 plus 87 equals 96.
3x what equals 87
What operation does 74 plus 13 equals 87 and 87-13 equals 74 demonstrate?
3 multiplied by 29 equals 87.
87 feet = 29 yards.
1 x 87, 3 x 29 = 87
5 + 87 = 92
29 x 3 = 87
3X = X + 58 subtract X from both sides 2X = 58 divide both sides by 2 X = 29 check 3(29) = 29 + 58 87 = 87 checks
29
it equals 406
