Hey there! :D
3. m • 5 = 125
To solve this problem, simply divide the quotient and the divisor of the given equation.
[tex]125 ÷ 5 = \boxed{\sf 25}[/tex]
Checking:
To check, simply substitute the conclusion on the unknown quantity.
25 (m) • 5 = 125
Thus, the equation was correct which gives us the answer that:
[tex]\large\boxed{ \sf \: m \: = \: 25}[/tex]

4. 99 = a ÷ 6
To solve this problem, we need to amend the given division as a fraction.
[tex]\sf 9 = \displaystyle \sf \: \frac{1}{6}[/tex]
Then, we'll have to multiply both aspects of the equation by 6 to get the value of a.
Thus, the value of a is 594.
[tex]\large\boxed{ \sf \: a = 594}[/tex]

5. 2x + 12 = 102
To get the value of x, simply first move the constant 12 to the right side of the equation and change its symbol.
2x = 102 - 12
Then, subtract the 102 from constant 12 whose value has been stridden.
2x = 90
Lastly, divide 90 by 2
Thus, the value of x is 45, and no more simplification can be done.
[tex]\large \boxed{ \sf \: x = 45}[/tex]
