Answer:
C
Step-by-step explanation:
It just says the difference between “a number” and 12. For an expression it has to have numbers grouped together
<em>1</em><em>/</em><em>2</em><em> </em><em>%</em><em>5</em><em>5</em><em>=</em><em>7</em><em>7</em><em> </em><em>sooooo</em><em> </em><em>here</em>
16 = -5 + z/4
21 = z/4
21*4 = z
z = 84
