Answer:
Yes
Step-by-step explanation:
So, the question is telling you, that if, x is equal to 43; is 43 + 42 = 85?
Notice how I replace x with it's numerical value, 43.
So, is 43 + 42 = 85?
Let's see:
43 + 42 = 85
85 = 85
Yup, 85 does equal 85. So, yes, x = 43 is a solution to x + 42 = 85.
A solution is when both sides match of the equal sign match. If both signs match, then it is a solution. 85 = 85; the left side matches the right side. Therefore, it is a solution.
If it doesn't match, for example 84 = 85, it is not a solution.
