It looks like you've uploaded a photo of math problems with various equations to solve. Let's go through the problems one by one. I'll start with the first few:

a) $5x = 15$

To solve for $x$, divide both sides of the equation by 5: $x = \frac{15}{5} = 3$

b) $12m = 48$

To solve for $m$, divide both sides by 12: $m = \frac{48}{12} = 4$

c) $32k = 128$

To solve for $k$, divide both sides by 32: $k = \frac{128}{32} = 4$

d) $6c = 9$

To solve for $c$, divide both sides by 6: $c = \frac{9}{6} = 1.5$

e) $2.6g = 7.8$

To solve for $g$, divide both sides by 2.6: $g = \frac{7.8}{2.6} = 3$

Would you like me to continue solving the rest, or would you like more details on any specific part? Let me know if you'd like me to go through the remaining problems or if you have any questions!

Here are five related questions for practice:

1. What is the solution to $7x = 21$?
2. Solve $4y = 16$ for $y$.
3. If $8z = 64$, what is $z$?
4. Solve for $a$ in the equation $3a = 18$.
5. What is the value of $n$ in the equation $9n = 72$?

Tip: When solving for a variable in a multiplication equation, always remember to divide both sides by the coefficient of the variable.
