Solve for x: x - 35 = 45 a. 10 b. 15 c. 35 d. 80

X = 80

Step-by-step explanation:

Add 35 To Both Sides

X - 35 + 35 = 45 + 35

Simplify

X = 80

Best Of Luck,

- I.A. -

The answer is D. 80.

A and B are incorrect because they're less than 35, meaning they'll give you a  negative number, and the answer we're trying to get is positive.

C is incorrect because it's the same number as the one subtracting x, so you'd only get 0.

That leaves D, and if you do the math, 80 - 35 is 45.
