3/4-(x+1/8)=5/16

3/4-x-1/8=5/16

3/4-1/8-5/16=x

Common denominator: 16

x=(4×3-2×1-5)/16=(12-2-5)/16=5/16

Answer: x=5/16

Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43

Now do the rest on your own!

17) x-8=11

18) 9-x=5

19) x+6=7

20) x+(-4)=-18

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

x-8=11

Solving:

x-8=11

x=11+8\\x=19

18) Nine less than a number is five.

Let number = x

then the equation will be:

9-x=5

Solving:

9-x=5\\-x=5-9\\-x=-4\\x=4

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

x+6=7

Solving:

x+6=7\\x=7-6\\x=1

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

x+(-4)=-18

solving:

x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14
