12 divided by 6 would be 12/6

3.5x + 7 = 1/2x - 6 (subtract 1/2x on both sides)

3x + 7 = -6   (subtract 7 on both sides)

3x = -13     (divide by 3 on both sides)

x = 4.333333333.....(you get the point :)

i know there is already answer, but i thought it would be helpful if i listed the steps

90877+33 would be 90910..

why didnt you use a calculator for such a simple addition problem?

5.297x10 in standard notation would be 52.97

Example: 7qr-qr=6qr

qr really means 1qr so you would subtract that numbers and then add the variable in.

Example: 9e - 5e = 4e
