Question

1.-3(n+5)=12

2.46=-6t-8

Answer 1

Distribute the -3 to what is in the parenthesis, to make -3n-15=12. Add the 15 to both sides, making -3n=27. Divide both sides by -3, to get n=-9.

Add 8 to both sides, making 54=-6t. Divide both sides by -6, to get t=-9.

The goal of questions like this is to get the variable by itself.
