Hasil dari – 40 + [ 20 × ( - 12) ] : 4 adalah ....

It's a simple linear equation in 'n'. There's only one number that 'n' can be that will make the equation a true statement. That number is called the 'solution' to the equation. Here's one way to find it:
You said that -7n - 4 = 24
Add 4 to each side: -7n = 28
Multiply each side by -1 : 7n = -28
Divide each side by 7 : n = -4
Homework is the only way for most people to learn stuff.

Add 4: -7n=28 Divide by -7: n=-4

To solve the equation -7n - 4 = 24, you add 4 to both sides, resulting in -7n = 28. Then, dividing by -7 gives you n = -4. The solution is verified by substituting back into the original equation.
