Answer:
83.55
Step-by-step explanation:
i think
First we have to get x by itself, so we multiply two on each side,
then we get 5x=660/4, I like to simplify here, so I would change it to 5x=165, then we divide each side by 5
x=33

Answer:
-10
Step-by-step explanation:
1. First, let's simplify both sides of the equation.
2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.
3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:
4. Now, with the information in #2, let's see if it's true:
-

-

- (0 = 0 means that the equation has infinitely many solutions)
Therefore, the missing number is -10.
