Answer 2

Here's how you solve for x:

3/8 (2x + 16) − 2 = 13
0.375(2x + 16) - 2 = 13
(0.375 * 2x) + (0.375 * 16) - 2 = 13
0.75x + 6 - 2 = 13
0.75x + 6 - 2 + 2 = 13 + 2
0.75x + 6 = 15
0.75x + 6 - 6 = 15 - 6
0.75x = 9
0.75x/0.75 = 9/0.75
x = 12

thank you

Answer 4

Okay, the first thing to do is to get the x term by itself. So we'll add 2 to both sides to get:
\[\frac{3}{8}(2x +16) = 13 + 2 =15\]
That x still has some stuff attached to it, let's get that 3/8 off by dividing both sides by 3/8:
\[(2x +16) = 15 \div \frac{3}{8} = 15 \times \frac{8}{3} = \frac{120}{3} = 40\]
Now we can move the 16:
\[2x = 40 -16 = 24\]
And divide both sides by 2:
\[x = 40 \div 2 = 12\]
Make sense? I finished it cause I'd already done most of the work, lol.

Just subtract 3.2 from both sides. You'll get a negative number with a magnitude bigger than -3.5.
