1/3 * x square = 16
x square =16*3
x square =48
therefore x=4 under root 3
You can think in reverse. Addition is the opposite of subtraction. So to solve 15-8, you can ask "8 plus what number is equal to 15?" and note how 8+7 = 15. So that's why 15-8 = 7. Similarly, 15-7 = 8 can be solved the same way.
10x-4-7/2x-3/4(2x-3)
6 1/2 -4 - 1 1/2x - 2 1/4
2 1/2- 1 1/2x- 2 1/4
1/4-1 1/2x
decimal form:
6.5-4-1.5x-2.25
2.5-1.5x-2.25
0.25-1.5x
