Question

-3/4x + 1/4x= -6
how would I work this problem?

Answer 1

first combine similar terms,, that is, add the numerical coefficient of x (or the number before x):
-3/4 + 1/4
*since they have the same denominator, you can add the numerator directly:
(-3+1)/4 = -2/4
it now becomes:
(-2/4)x = -6
now, we can multiply -1 to both sides to cancel out the negative:
(2/4)x = 6
divide the 6 by (2/4) to get x alone:
x = 6 / (2/4)
to divide a number by a fraction, get first the reciprocal of the fraction,, that is you just have to interchange the numerator and denominator:
2/4 --> reciprocal is 4/2
now the operation becomes multiplication instead of division:
x = 6 / (2/4)
x = 6 * (4/2)

now solve for x. :)

Answer 2

add -3/4 to -3/4 to cancel it out then add -3/4 to -6 so you have 1/4x=-1.5 divide 1/4 by 1/4 to get the x alone then divide -1.5 by 1/4 and whatever that comes out to be equals x

Answer 3

x= 12 :D

Answer 4

yes! that's right~! :)
