How do you solve #4.2m+4=2.5#?

Answer 1

The equation is still valid if you apply the same fundamental arithmetic operation to both sizes, with the exception of trying to divide by zero.

Starting with #4.2 m + 4 = 2.5#

Subtract #4# from both sides of the equation: #4.2 m = -1.5#

Divide both sides by #4.2# # m =- 5/14 = -0.3571...#

To solve the equation 4.2m + 4 = 2.5, you first subtract 4 from both sides to isolate the term with the variable. Then, divide both sides by 4.2 to solve for m. The solution is m = -0.547619048.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
