start by diving 5 from each side so you are lrft with x on the left side, 40/5=8. now our equation is x=8 and that's the answer!
.09 chance that <span>the land has oil and the test predicts that there is no oil.</span>
<span>5x+10 = y
Subtract 10 from both sides.
5x = y - 10
Divide both sides by 5.
x = 1/5y - 2
Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y
1 = y
