The area of triangle formula is A = B*H  / 2
so it means 16 square = (<span>x+4) x /2
so x²+4x -32=0, D' = 2²- (-32)= 36, sqrt of D' = 6
so x = -2 -6 = -8 or x= -2 +6 = 4
x must be positive so x = 4</span>

Help with how to do these step by step?
zimovet [89]
Okay, so slope intercept form is y=mx+b. Like a normal problem with numbers, you add or subtract from each side. 
3x-2y= -16
you want to leave the y by itsself, so your going to add 3x to 16, but write it out how the formula is (y=mx+b). now, you should have -2y= -3x-16. (the three is now negative because you moved it to the other side of the equation.) 

now, remember that you want the y all by itself, so, all you have to do now is divide. 
-2y= -3x-16 ---------- now is y= -3/-2x minus 16/-2. (those are now fractions, but the y is alone.) now you simplify. 
-3/-2x is already simplified, but 16/-2 is not so it changes into -8,after dividing the fraction. 
now you have the answer. 
y= -3/2x-8x (it is the same as the formula now!)

hope this helps! it was hard to explain through typing but if you read it carefully, i explained every step.
