Answer: n=3.8
Explanation:
It is long but does a good job of explaining it
Let's solve your equation step-by-step.
0.3(n−5)=0.4−0.2n
Step 1: Simplify both sides of the equation.
0.3(n−5)=0.4−0.2n
(0.3)(n)+(0.3)(−5)=0.4+−0.2n(Distribute)
0.3n+−1.5=0.4+−0.2n
0.3n−1.5=−0.2n+0.4
Step 2: Add 0.2n to both sides.
0.3n−1.5+0.2n=−0.2n+0.4+0.2n
0.5n−1.5=0.4
Step 3: Add 1.5 to both sides.
0.5n−1.5+1.5=0.4+1.5
0.5n=1.9
Step 4: Divide both sides by 0.5.
0.5n
0.5
=
1.9
0.5
n=3.8
