Question

1/4 (20x+8)+3=0 show work

Answer 1

So, you need to do the same operation to each side.
Start out by subtracting 3 from each side
1/4 (20x+8) = -3
Then, multiply both sides by 4
40x+8 = -12
Then, subtract 8 from each side
40x = -20
divide both sides by 40 and you get
x=-1/2

Hope this helped!

Answer 2

The first thing you should do is distribute 1/4 into (20x+8). You should do this first because of the order of operations:

Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction

5x+2+3=0

Add 2 and 3 together

5x+5=0

Subtract 5 from each side.

5x=-5

Finally, divide each side by 5

x=-1

To check our answer, substitute -1 in as x

1/4(20(-1)+8)+3=0
1/4(-20+8)+3=0
1/4(-12)+3=0
-3+3=0
0=0

x=-1
