Question

solve the equation pls and translate the sentence
the sum of 15 and 7 times a number is 99

Answer 1

how would you interpret 7 times a number?

Answer 2

As 7 times a number indicates multiplication:
\[15 + 7x = 99\]
That would read 15 and (+) 7 times a number (where x is our number) is equal to 99.
Moving 15 to the other side:
\[7x=84\]
Then simply divide 84 and 7 to find x.
