Question

Please help me!!!!!Q!!!!!!!

Answer 1

-2.1 - x = -1.5

-x = .6

x = -0.6

answer: C

Answer 2

We are given the equation:

${:\implies \quad \sf -2.1-\underline{?}=-1\dfrac12}$

Let assume the unknown value be x, so that:

${:\implies \quad \sf -2.1-x=-\dfrac32}$

${:\implies \quad \sf x-1.5=-2.1}$

${:\implies \quad \sf x=1.5-2.1=\boxed{\bf -0.6}}$

Hence, Option c) is correct
