Answer:
85 - 9Y = 7(4 + Y)
Step-by-step explanation:
Nine times a number Y. = 9 * Y = 9Y
subtracted From 85 = 85 - 9Y........... Equation 1
seven times sum of 4 and Y = 7(4 + Y)....... Equation 2
Equate Equation 1 and 2
85 - 9Y = 7(4 + Y)
The equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation in the word is "Nine times a number y subtracted from 85 is seven times the sum of four and y"
Let the number is y:
The nine times a number = 9y
Subtract from 85:
85 - 9y
Seven times the sum of 4 and y = 7(4 + y)
Now on equating:
85 - 9y = 7(4 + y)
Thus, the equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).
