Answer: n=5.666667
Step 1: Simplify both sides of the equation.
0.3(n−5)=0.4−0.2
(0.3)(n)+(0.3)(−5)=0.4+−0.2(Distribute)
0.3n+−1.5=0.4+−0.2
0.3n−1.5=(0.4+−0.2)(Combine Like Terms)
0.3n−1.5=0.2
0.3n−1.5=0.2
Step 2: Add 1.5 to both sides.
0.3n−1.5+1.5=0.2+1.5
0.3n=1.7
Step 3: Divide both sides by 0.3.
0.3n/0.3 = 1.7/0.3
n=5.666667
