25X + 30 = 15X
subtract 15X from each side
25X - 15X + 30 = 15X - 15X
10X + 30 = 0
subtract 30 from each side
10X + 30 - 30 = 0 - 30
10X = -30
divide both sides integers by 10
(10/10)X = - 30/10
X = - 3
----------------check in original equation
25(- 3) + 30 = 15(- 3)
- 75 + 30 = - 45
- 45 = - 45

5x2 + 25x + 30 This expression describes a parabola, and can be factored out as follows: = 5(x2 + 5x + 6) = 5(x + 2)(x + 3)
This is a quadratic equation in the form of: 52 - 25x + 30 = 0 Solve by using the quadratic equation formula: x = 2 or x = 3 Or by factorising: (5x-10)(x-3) = 0, which means that x = 10/5 or x = 3
Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.
There's nothing to solve, it's simply an expression.

If you mean: 10+4r = 30 then it works out that r = 5
(5x + 10)(x + 3) or 5. (x + 2)(x + 3) Check with x = (say) 3 so 5 x 5 x 6 = 150; 45 + 75 + 30 = 150 OK
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
45 = 30 + m Subtract 30 from both sides: 15 = m
4x2=8 8+22=30 You get 30 it really is simple
