5x-x=36 4x=36 x=36/4 x=9
If you mean (5x+3)2 = 36... 5x+3 must equal 6 so - 5x has to equal 3 - therefore x = 0.6
(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
x = 1

sorry i am not sure but i dont think it has an answer If this equation is: x^2 - 36 = 5x, then: x^2 - 36 = 5x subtract 5x to both sides; x^2 - 5x - 36 = 0 Factor; (x + 4)(x - 9) = 0 x + 4 = 0 or x - 9 = 0 x = -4 or x = 9
(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
When factored it is: (x-9)(x+4)
5x-2x=9
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
x2-5x-36 = (x-9(x+4) when factored
x = 1
5x-2x=9
5x-x=36 4x=36 x=36/4 x=9
3x + 9 = 54 - 2x Subtract '9' from both sides Hence 3x = 45 - 2x Add '2x' to both sides 5x = 45 Divide both sides by '5' x = 9 The answer!!!!! Verification 3(9) + 9 = 27 + 9 = 36 & 54 - 2(9) = 54 - 18 = 36 Hence both sides are equal at '36'.
