If 3 times a certain number is increased by 4 the result is 28 what is the number

Answers

Answer 1

Answer:

Answer: The number is 8

Step-by-step explanation:

Let be "x" the certain number. Then "3 times a certain number" means that the number "x" is multiplied by 3. This is:

$(3)(x)=3x$

Now, "3 times a certain number is increased by 4" means that the we must add 4 to $3x$ , in other words, this indicate an addition:

$3x+4$

And finally "3 times a certain number is increased by 4 the result is 28" means that $3x+4$ is equal to 28. Then the expression is:

$3x+4=28$

To find the number "x", subtract 4 from both sides of the equation:

$3x+4-4=28-4$

$3x=24$

Dividing both sides of the equation by 3, you get that the number is:

$(3x)/(3)=(24)/(3)\n\nx=8$

Answer 2

Answer: 3x+4=28
-4 -4
3x=24
/3 /3
x=8

Answer:

5 - 2x

Step-by-step explanation:

Translating words to numbers can be tricky.

Here it says: "5 decreased by twice a number." So you have to imagine-- I started with Five things. Then there was a decrease --twice some variable.

5 take away twice something translates to

5 - 2x

Tricky, because most algebra expressions are written with variables first, then the constants. You could rewrite this expression as

-2x + 5
