1. m’+9 = 58m=2. 7e² = 28erd=3. d? + 6 = 704 n - 10 = 62n=

For this case we must solve each of the equations proposed:

A)

Subtracting 9 from both sides of the equation we have:

Applying root to both sides of the equation:

B)

We divide between 7 on both sides of the equation:

We apply root to both sides of the equation:

C)

Subtracting 6 on both sides of the equation:

We apply root to both sides of the equation:

D)

We add 10 to both sides of the equation:

We multiply by 2 both sides of the equation:

We apply root to both sides of the equation:
