7.

find a common denominator
it will turn into 54 over 45 times -50 over 45
multiply across, leaving the denominator the same
divide the numerator by the denominator
leaving you with 60
ANSWER: 60
8.

Turn the whole number into a fraction by multiplying 3 by 8, also write an 8 under your answer, put the negative in front of the fraction
now we have -24 over 8 divided by 7 over 8
divide -24 by 7
now we have -3 over 8
ANSWER=
Answer:
x = 16.5
Step-by-step explanation:
Firstly, open the brackets
6÷15x- 45 = 2÷3x+18
Rewrite the equation as:
6/15x-45 = 2/3x+18
cross multiply
6×3x+18 = 2×15x-45
18x+108 = 30x-90
collect like terms
18x-30x = -90-108
-12x = -198
divide both sides by -12
-12x/-12 = -198/-12
x = 33/2
x = 16.5
One solution was found : x = 5/7 = 0.714
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-1/2*x+1/3-(1/5*x-1/6)=0
