Answer:
x = -5
Step-by-step explanation:
In both questions you want to get the x alone.
1.
-3x + (-6) = 9
First you want to add 6 to both sides so you'll be left with:
-3x = 15
Next, you want to divide both sides by -3 and you'll get:
x = -5
2.
-4x + (-12) = 8
You want to do the same thing as the first one so you'll add 12 to both sides:
-4x = 20
Then, you will divide both sides by -4 and get:
x = -5
First the equation would look like this:
7n = 5n - 3
7n - 5n = 5n - 5n - 3 -Subtract 5n from both sides. Which gives you...
2n = -3
2n/2 = -3/2 -Divide both sides by 2
n = -1.5
Hope this helps!
