There is no formula to algebra. If there were a formula, then it would have to be to do the reverse of the order of operations. For example, (3x)3 over 2=9 to figure this out, work backwards (3x)3 over 2 divided by 2=9/2 (3x)3=4.5 the square root of (3x)3=sqrt 4.5 3x=sqrt 4.5 3x/3=(sqrt 4.5)/3 x=(sqrt 4.5)/3 Technically, there is no formula, but seriously, the formula is to work backwards. Now, the problem has been turned from algebra to problem solving.
If this is algebra then; 3x plus 12x = 15x
3x-2x+4x1x+4x5x
Let the unknown number be x: 13x-119 = 3x-9 13x-3x = -9+119 10x = 110 x = 11 Substituting the value of x into original equation: 24 = 24

3x - 7 ≤ 9 "Seven less than" means that you subtract seven from the answer. "Three times a number" means that you multiply it. "At most" means that this is the greatest number that it can be, which is, in this case, 9. To solve this, you apply the principle rules of algebra to determine x. 3x ≤ 9 + 7 3x ≤ 16 x ≤ 16/3

you multiply by its denominator to each side. Example: 3x/5=9 now multiply by 5 to each side 3x/5 times 5 is 3x and 9 times 5 is 45 so you get 3x=45 now divide by 3 to each side and you get x=15
3x
x = 7
If this is algebra then; 3x plus 12x = 15x
3x-2x+4x1x+4x5x
Algebra is the basis of maths you can use it to solve unknown terms such as x. For example: 3x - 3 = 0 3x = 3 x = 1
Using algebra the number works out as 25
Let the unknown number be x: 13x-119 = 3x-9 13x-3x = -9+119 10x = 110 x = 11 Substituting the value of x into original equation: 24 = 24

There are many uses of algebra. Algebra is used mosty to find the value of the variable in a mathematic situation. Example- 3x=66 (divide by 3x on both sides)= 66/ by 3 is 22 solution- x=22 ----
