To solve the equation x + 30 = 90, we need to isolate the variable x. Here's the step-by-step solution:
Step 1: Start by subtracting 30 from both sides of the equation to move the constant term to the other side:
x + 30 - 30 = 90 - 30
x = 60
Therefore, the value of x that satisfies the equation is 60.
To arrive at this solution, we subtracted 30 from both sides of the equation. This is because subtracting the same value from both sides of an equation maintains equality.
Here's a summary of the steps:
x + 30 - 30 = 90 - 30
x = 60
