3(2x - 3) = 4x + 1 Help

Mathematics

Answer:

x=5

Step-by-step explanation:

You first have to distribute. So multiply the 3 with whats inside the parenthesis. So 3 times 2x is 6x. And 3 times -3 is -9. That means that so far you have 6x-9. Now on the other side you have 4x+1. So you move the 9 over to the other side by doing the opposite of it. Meaning +9. So you add 9 to 1 giving you 10. Now you have, 6x=4x+10. Just subtract 4x from 6x, which gives you 2x. Lastly, you divide the 10 by 2x because division is the opposite of multiplication

3(2x - 3) = 4x + 1

multiply the bracket by 3

(3)(2x)=6x

(3)(-3)=-9

6x-9=4x+1

move +4x to the other side

sign changes from +4x to -4x

6x-4x-9=4x-4x+1

6x-4x=2x ( combine like terms)

2x-9=1

move -9 to the other side

2x-9+9=1+9

2x=1+9

2x=10/2

divide both sides by 2 to get x by itself

2x/2=10/2

cross out 2 and 2, divide by 2

then becomes 1*1*x=x

divide by 2 for 10/2

10/2=5

2/2=1

5*1=5

Answer:

x=5

andrew11 [14]

Answer:

2b < 56

n = b - 2

b = n + 2

n < 27

b < 28

No, because the difference between Brittany and Nate's age is 2years

Step-by-step explanation:

A.)

Twice Brittany’s age is less than the age of Abraham Lincoln when he died. President Lincoln was 56 years old at the time of his death

Let Brittany's age = b

Twice Brittany's age = 2 × b = 2b

Lincoln's age = 56

2b < 56

B.)

Nate's age = n

Nate is 2 years younger than brittany who is aged 'b'

n = b - 2

C.) b = n + 2

D.)

If 2b < 56 and b = n + 2

2(n + 2) < 56

2n + 2 < 56

2n < 56 - 2

2n < 54 ; n < 27

2b < 56

b < 56/2

b < 28

No, because the difference between Brittany and Nate's age is 2years
