You can distribute the q to both terms to get

The product (multiply) of a number (x) and four (4) is at most (≤) -10.
4x ≤ -10
To solve this, divide both sides by 4
x ≤ -2
It’s in scientific, currently. So you want to put it back the way you’d write it normally. Move the decimal two places to the right (bc x 10^2) to get 338.55
X=3/5
do you need an explanation?
