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
9 plus 87 equals 96.
3x what equals 87
Well, let's imagine numbers as friends playing on a see-saw. When we add 74 and 13 together, it's like lifting one friend higher on the see-saw, making the total 87. Then, when we subtract 13 from 87, it's like bringing that friend back down to the same level as the other, which gives us back our original number of 74. It's all about balancing the numbers, just like friends on a see-saw!
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
