Answer:
C on edge 2021
Step-by-step explanation:
7-(p+t) = 9(85-n) = 7(4+y)
Algebra is a kind of mathematics that includes symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables.
An algebra expression contain coefficient variable and a constant
We apply various methods to solve those question
An algebra expression is also called an equation
let the number be x
Seven less than the of p and t
= 7-(p+t)…….(1)
Nine times a number y subtracted from 85
= 9(85-n)…..(2)
Seven times the sum of four and y
= 7(4+y)……(3)
Combining equations (1), (2) and (3) according to the question :
7-(p+t) = 9(85-n) = 7(4+y)
