.t=50 +d so the answer is d
Step-by-step
=> 900=-100x+300
=> -100x+300=900
=> -100x=900–300
=> -100x=600 divide both side by -100
=> x=-6
The answer is A) X=3
First we remove five from each side
Now the equation is 3x = 9
Let's get X by itself
Here we can divide both sides by 3
So your answer is x=3
