80-x+145=135
To find the value of x, we need to isolate the variable on one side of the equation.
Starting with the given equation:
80 - x + 145 = 135
Combine like terms on the left side:
225 - x = 135
Now, we want to move the constant term to the other side:
225 - x - 225 = 135 - 225
Simplifying:
-x = -90
To solve for x, we need to isolate the variable, so we multiply both sides by -1:
-x * (-1) = -90 * (-1)
This gives us:
x = 90
Thus, the value of x is 90.
