Step-by-step explanation:

-7(1+3x) = 4 + 5x

-7 - 21x = 4 + 5x

(get all the variables on one side. Don't forget to change the signs)

-7-4 = 5x + 21x

-11 = 26x

(divide both sides by the coefficient [26])

26x/26= -11/26

x = -11/26

Which number line repersents the sum of 1.25+(-0.75

aleksklad [387]

Answer: See explanation

Step-by-step explanation:

You didn't give the options relating to the question.

To solve this first, you need to know that we have to note that (+) × (-) = (-). Therefore, 1.25+(-0.75) will be thesame as writing 1.25 - 0.75. This will then be:

= 1.25 - 0.75

= 0.50

7 times what equals 1?

Arturiano [62]

For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:
$(7) (x) = 1
$
From here, we clear the value of x.
We have then:
$x = \frac{1}{7} 
$
Therefore, we have:
$(7) ( \frac{1}{7} ) = 1
$
Answer:
7 times 1/7 equals 1

If 2(4x + 3) -12 = 3x -6, then what value of x makes the equation true ?

poizon [28]

x=0

let's solve your equation step-by-step

2(4x+3)-12=3x-6

(8x)+(6-12)=3x-6

8x-6=3x-6

subtract 3x from both sides.

8x-6-3x=3x-6-3x

5x-6+6=-6+6

5x=0

5x/5=0/5

x=0

I hope that helps you
