-3(1-2x)-3=-20-8x what is the work and answer
larisa86 [58]
You have to keep order of operations in mind.

1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x

2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14

3. Solve for x.
Divide by 14 on both sides.
x=-1

for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal
\frac{43}{20}


35.G
if you divide
58 \div 25 = 2.32
so G
\frac{58}{25}

36. C
\frac{5}{5}  = 1
so if you subtract
\frac{6}{5}  -  \frac{5}{5}
will equal

\frac{1}{5}
1 \frac{1}{5}
