Answer:'r + 75 = 200'
Explanation:
Given,
No. of pages read by James = r
No. of pages read by Simon = 75
Total pages read by them = 200
So, the equation would be:
r + 75 = 200
To find,
No. of pages read by James,
By subtracting 75 from both sides,
r + 75 - 75 = 200 - 75
r = 125
To verify,
125 + 75 = 200
200 = 200
