12a + 4 - 10a = 2a + 4 or 2*(a + 2)

10a+a

50 - 3 = 47

10a + 3a - 4a = 9a

(a + 6)(a + 4)

to solve this expression: 10a-4(a+2) -> 10a-4(a)-4(2) -> 10a-4a-8 -> 6a-8

10a + 15 = 5 (2a + 3)

10a + 5b

10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5

6a-10a=16 -4a=16 a=-4

2a + 5a + 3a = 10a

12a + a - 3a = 10a

10a * (a + 2)

10a - 10 b

It is not an equation but an algebraic expression that can be simplified to: 12b-5a

5a(a+2) = 5a^2 + 10a

To multiply m x 10a by n x 10b: multiply the numbers (m x n) add the powers (a + b) (m x 10a) x (n x 10b) = mn x 10a+b To divide m x 10a by n x 10b: divide the numbers (m / n) subtract the powers (a - b) (m x 10a) / (n x 10b) = m/n x 10a-b
