Answer:
x=5
Step-by-step explanation:
First combine like terms
8x-8=4x+12
Move -8 over to the other side, it becomes +8
8x=4x+20
Now subtract 4x from 8x
4x=20
Now divide
20÷4=5
x=5
Answer:
It's the first one.
Step-by-step explanation:
a + b = 88 <span>
<span>
</span><span>ab = y
</span><span>
</span><span>a = 88 - b
</span><span>
</span><span>y = (88 - b)*b
</span>
<span>y = -b^2 + 88b
</span><span>
</span><span>Take the derivative and set equal to 0
</span><span>
</span><span>y' = -2b + 88 = 0
</span><span>
</span><span>2b = 88
</span>
<span>b = 44 </span></span>
<span><span>a=44</span></span>
<span><span> both numbers are 44</span></span>
