0.3(n-5)=0.4-0.2n solve for n

n=3.8

Step-by-step 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

answer: 2 and 1
