Question

assignment
solve each equation.

  1. $-31 = x + -13$
  1. $-5 = k + 1$
  1. $-12 = -4 - k$
  1. $2 + n = -10 - 2n$
  1. $-5b - 1 + 8 = -8b - 11$

Explanation:

1) Solve \(-31 = x + (-13)\)

Step1: Simplify the equation

The equation is \(-31=x - 13\) (since \(x+(- 13)=x - 13\)).

Step2: Isolate \(x\)

Add \(13\) to both sides of the equation.
\(-31 + 13=x-13 + 13\)
\(-18=x\)

Step1: Isolate \(k\)

Subtract \(1\) from both sides of the equation.
\(-5-1=k + 1-1\)

Step2: Simplify

\(-6 = k\)

Step1: Isolate the term with \(k\)

Add \(k\) to both sides: \(-12 + k=-4-k + k\), which simplifies to \(-12 + k=-4\)

Step2: Isolate \(k\)

Add \(12\) to both sides: \(-12 + k+12=-4 + 12\)
\(k = 8\)

Answer:

\(x=-18\)

3) Solve \(-5=k + 1\)
