Need to divide both sides of the equations by -4 and it’s going to give you this m+6=2. Then move the constant to the right-hand side and change its sign and it’s going to give you this m=2-6. And then calculate the difference and then it’s going to give you this m=-4.
The answer to the question is 15x+30-64
Answer:
Hmm...A would be 1 and B would be 3x.

Answer:80
Assume the number to be 400 for instance,
10% of 400 increased = 400 + ( 10/100 × 400 )
= 400 + 40 = 440
The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
