Answer:
Step-by-step explanation:
The number of questions on a math test is represented (3x+1). The number of questions on the spelling test is represented by (x+12).
An expression to find how many more questions were on the math test would be
= 3x + 1 - (x + 12)
= 3x + 1 - x - 12
= 3x - x + 1 - 12
= 2x - 11
When the value of x = 8, then the expression becomes
2× 8 - 11 = 16 - 11 = 5
