    need to do the operations in the bracket first.

    \[-4.5[2x-(0.5-1.4)]\]

    so taking the bracket first.. we noticed that there is a parenthesis so we need to compute 0.5-1.4 first

    Yes, this is a question of knowing PEDMAS/ BEDMAS, what ever the kids call it these days.

    US education system uses PEMDAS but often forget that when there is [ () ] the bracket is taken first into consideration and then do the problem in (I)

    I'm just waiting for the OP to respond to what's 0.5-1.4

    I don't want to be one of those people with A is the answer or 1239 here's the link to an online calculator.

    thanks :). I caught someone using an algebra calculator and citing it as the source of the answer.

    By the way, PEDMAS stands for P = parenthesis E = exponents D = division M = multiplication A = addition S = subtraction Going in that order for the operation :P, just a little note if OP doesn't know haha.

    we're helping you solve it \[-4.5[2x-(0.5-1.4)] \] we consider the bracket first then since there is a () and P is present we need to solve 0.5-1.4

    Sorry to intrude like that Usuki, I will let you continue, good luck :)

    so what is 0.5-1.4 ?

    -0.9

    yes

    \[-4.5[2x-(-0.9)]\]

    now we need to distribute the negative so -0.9 becomes positive

    \[-4.5[2x+0.9]\] we can't combine 2x and 0.9 because x is a variable and we have a constant (a number) so we can go ahead and distribute the -4.5 throughout the whole equation

    so what is -4.5(2x) same as -4.5 times 2x and -4.5 x 0.9

  25. UsukiDoll

    you just have to compute -4.5 x 0.9 and -4.5(2x)

  26. UsukiDoll

    and then by doing those computations... this is the answer -9x-4.05
