Answer:

x=-3/4

Step-by-step explanation:

Use the <u>distributive</u> property <u>a(a+b)= ab+bc</u>:

-4x-2=1

Add a 2 to both sides:

-4x=3

Divide both sides by -4:

x=3/-4

This can be rewritten as -3/4

How do you divide 3.4÷12.92

Travka [436]

Well 3.4 goes into the house and 12.92 is outside of it. 3.4 is a smaller number so you'd add zeros to get the 12.92 into 3.4. As you add zeros you'd take the decimals out and move them to the right two times. But u actually move the decimal first than adding zeros. Step 1: Take out the decimals. Step 2: Add the zeros. Step 3: Hope this helped.
