Answer 1

@Qwertty123

Answer 2

Combine like terms

13 + 6 = ?

Answer 3

Yes you would want to
Combine like terms: 13 + 6 =?

Answer 4

19

Answer 5

alright so we have

19 - 3x = 4b

Answer 6

Move all terms containing b to the left, all other terms to the right.
Now what do you do to get b by itself?

Answer 7

add -4?

Answer 8

yes, you now add '-4b' to each side of the equation.
19 + -4b + -3x = 4b + -4b

Answer 9

Combine like terms: 4b + -4b =?

Answer 10

0

Answer 11

yes,
19 + -4b + -3x = 0

Answer 12

add -19?

Answer 13

Yes!
Add '-19' to each side of the equation.
19 + -4b + -19 + -3x = 0 + -19
Reorder the terms:
19 + -19 + -4b + -3x = 0 + -19

Combine like terms: 19 + -19 =?

Answer 14

0

Answer 15

yes okay so it looks like this after we...
Combine like terms: 19 + -19 = 0
0 + -4b + -3x = 0 + -19
-4b + -3x = 0 + -19

Combine like terms: 0 + -19 = ?

Answer 16

-19

Answer 17

so now would you add 3?

Answer 18

yes!
Now Add '3x' to each side of the equation.
-4b + -3x + 3x = -19 + 3x

Combine like terms: -3x + 3x =?

Answer 19

0

Answer 20

yes -4b + 0 = -19 + 3x
-4b = -19 + 3x

Answer 21

DIVIDE -4?

Answer 22

yes, Divide each side by '-4'. What do you get?

Answer 23

Once you have a solution, you might want to determine whether there's a quicker way to solve this equation for b.

If 13+6-3x=4b, then 19-3x=4b.
Must enlose that "19-3x) within parentheses. Then divide that quantity (within parentheses) by 4. Done.
