Mathematics

Fofino [41]2 years ago

Answer:

2

Step-by-step explanation:

4x+3−x=12x−15

<u>Combine 4x and −x to get 3x</u>.

3x+3=12x−15

<u>Subtract 12x from both sides</u>.

3x+3−12x=−15

<u>Combine 3x and −12x to get −9x</u>.

−9x+3=−15

<u>Subtract 3 from both sides</u>.

−9x=−15−3

<u>Subtract 3 from −15 to get −18</u>.

−9x=−18

<u>Divide both sides by −9.</u>

x= –18÷–9

<u>Divide −18 by −9 to get 2.</u>

x=2

elena-s [515]

Answer:

28, 29, and 30

Step-by-step explanation:

There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.
