The difference between a number and 7 is greater than -23
Aleks04 [339]
-23 is a negative number so that means 7 is a greater number. any number with a minus sign like this - means it’s a negative number, so any number that you have to compare it to and if that number has nothing before or after it, then that would be the greater number

An equation is shown below: −2(4x − 1) − 7 = 5 Which statement shows a correct next step in solving the equation?
LuckyWell [14K]
B. The equation can become −2(4x − 1) = 12 by applying the addition property of equality because we have: <span>−2(4x − 1) − 7 = 5 / + 7 <=> -2(4x-1) = 12;</span>

What is the anwser to 3(x-1)-8=4(1+x)+5
Fynjy0 [20]

X=20

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

1. Distribute

3x-3-8= 4+4x+5

2. Combine like terms

3x-11=4x+9

3. Add 11 or subtract 9 to both sides

3x-11+11=4x+9+11

or

3x-11-9=4x+9-9

3x=4x+20

or

3x-20=4x

If you did the first step then you subtract 4x from both sides

3x-4x=4x+20-4x

-x=20

Then you would divide by a negative 1 because there is an imagery 1 in front of the x.

-x/-1=20/-1

x=-20

If you did the second way then you would subtract 3x from both sides

3x-20-3x=4x-3x

-20=x

And you get the same answer for both ways
