Answer:
x = -10
Step-by-step explanation:
move all the constants (numbers without variables) to one side to get

-4x = 40
multiply by -1
4x = -40
divide by 4
x = -10
Answer:
4 + 2 = 6
5 + 5 + 9 + 8 + 90+ 90 - 1000 = -793

becomes

Now we need to isolate x. Remember PEMDAS?


Simplify the right side.

Answer:
3s + 3t
Step-by-step explanation:
To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:
(s + t) * 3 =
3s + 3t
And that is the simplified form for this expression.
Hope this helps :)
