1. 150 + x = 300

A. 200
B. 150**
C. 50
D. 190

The answer is B. 150+150=300, if you wanted to show your work it would be as follows

150+x=300

150+x=300

Okay sorry about that... Keep pushing shortcut key lol. Ok so it would be 150+x=300

-150
x=150

Thank you :)

To solve the equation 150 + x = 300, you need to isolate the variable x on one side of the equation.

Here's how you can do it:

1. Start with the equation 150 + x = 300.
2. To isolate x, subtract 150 from both sides of the equation.
150 + x - 150 = 300 - 150
x = 150

Therefore, the value of x that satisfies the equation 150 + x = 300 is x = 150.

So, the correct answer is B. 150.
