Answer:
3.7
Step-by-step explanation:
1. 2 = m - 2.5
m =?
from the question simple arithmetic will be applied by simply collecting the like terms together
therefore; m = 1.2 + 2.5
m = 3.7
1

Add 2 to both sides:

Divide both sides by -4 (this is negative, so we have to swap the inequality sign):

2

Expand the left hand side:

Add 8 and y to both sides:

Divide both sides by 3

3-4
Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them
