Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

$\frac{1}{3}$ × $\frac{7}{7}$ = $\frac{7}{21}$ $\frac{3}{7}$ × $\frac{3}{3}$ = $\frac{9}{21}$

To solve the equation 7 = 3x-2 for x, what operations

Aleks [24]

X=3

Algebra is not one of my fav subjects in math but I do know this!

when solving what you do to one side you do to the other so

if 3x-2=7

the 2 is negative so you change that -2 into a positive

so add 2 to both sides

7+2=9

3x=9

now divide both sides by 3

X= 9/3 (nine over three)

now divide 9 by 3

9÷3=3

x=3

(Hope this helps!)

B-4-3b combining like terms

Bogdan [553]

Answer: -2b-4

Ok, so I assume you meant b-4-3b. If not, then B-4-3b is the best you can get, since B and b are different in math.

Anyways, we can rearrange b-4-3b into b-3b-4. Calculating b-3b = -2b. That means -2b-4 is the answer.

Hope that helped,
