Given that: step 1

$3x+12=8x-18$

step 2: subtract 3x both side

$\begin{gathered} 3x+12-3x=8x-3x-18 \\ 12=5x-18 \end{gathered}$

Step 3: Add 18 both side:

$\begin{gathered} 12+18=5x-18+18 \\ 30=5x \end{gathered}$

Step 4: divide both side by 5

$\begin{gathered} \frac{30}{5}=\frac{5x}{5} \\ 6=x \end{gathered}$

Step:6 The value of x is:

A triangles three angles always sum up to 180 degrees. We must find angle B.

We already have angle A and C, so it's quite simple.

Angle A is 28*, and angle C is 36*

We add these two together

28 + 36 = 64

Now we subtract

180 - 64 = 116

Angle B = 116*

Hope this helps you! (:
