Let's solve :
6x = 72`

Let's solve : 2x - 5{7 - (x - 6) + 3x} - 28 = 39

Let's solve : 9x + 2 = 20

Let's solve : 4x - 2x + 3 = 9 - 4x

Let's solve : frac(x)(4) - frac(x)(2) = 3frac(1)(2) - frac(x)(3)

Using formula let's show that. (6x + 7y)^2 - 84xy = 36x^2 + 49y^2

Let's solve : frac(1)(3)(x-2) + frac(1)(4) (x + 3) = frac(1)(5)(x + 4) + 15

Let's solve the following equation. 6x = 7

Let's solve the following equation. 2x + 0.06x - 6.6 = 0.4x

Using formula, let's solve each of the following problems- If 6x^2 - 1 = 4x , let's show (36x^2 + frac(1)(x^2)) = 28

Let's solve the following equation. 5(x+3) + 4(2x+6) = 0
