@RJB948468940353 @Allie777Luck @hibanoorie “It only increased by 10 and not x2“? 19 + 10 is not 39

@hridduSP 9(X+4)=81 divide by 9
X+4=9 subtract 4
X=5

@hridduSP 5

@JAlbert0ltq @Im___maryam The really sneaky people will start including the negative numbers as well, like √9=-3. That gives many possibilities.

@JAlbert0ltq @_alee__sha_ You don't actually need to work out what √144 is. It can be written as 4x√144 over 2x√144 Which means the √just cancels out. Really useful technique if it was some oddball number in the square root.

[Avid 618 @Avid618R]

@_alee__sha_ What that means is even if it was a ridiculously hard to √ number (eg √1.379) it doesn't matter it's still just as easy to get the answer, which would still be 2.

[Avid 618 @Avid618R]

@_alee__sha_ It can be rearranged to 4x√144 over 2x√144 as the √144 is common to both top and bottom they cancel each other out, so you don't even need to be able to calculate √144. That leaves 4/2 or 2

@Allie777Luck @RJB948468940353 @hibanoorie Different people spot different things. I'm in the x2+1 camp myself. Yours was a completely new idea to me.

@hibanoorie 79 Yx2+1

@Michael94031523 @_alee__sha_ Half right?

[Avid 618 @Avid618R]

@_alee__sha_ @tek_sidhu Is 15 between 20 and 30 where you live?

[Avid 618 @Avid618R]

@tek_sidhu 24

[Avid 618 @Avid618R]

@_alee__sha_ 3(x+3)=30 divide both sides by 3
x+3=10 subtract 3 both sides
x=7
