5x+3-45 = 6x+9-30/1
what is the value of x
-21
To find the value of x, we can start by simplifying the equation:
5x + 3 - 45 = 6x + 9 - 30/1
Combine like terms on both sides of the equation:
5x - 42 = 6x - 21
Next, we want to eliminate the variable (x) from one side of the equation. We can do this by subtracting 5x from both sides:
5x - 5x - 42 = 6x - 5x - 21
Simplifying further:
-42 = x - 21
Now, let's isolate x by adding 21 to both sides:
-42 + 21 = x - 21 + 21
Simplifying again:
-21 = x
Therefore, the value of x is -21.
