y= 4x +6
_______
x + y = 90
4x − y = -6
The equations are [tex]\rm x + y = 90[/tex] and [tex]\rm 4x - y = -6[/tex]. Then the correct option is B.
What is the linear system?
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The sum of x and y is 90.
And y is 6 more than four times x.
Let x and y be the numbers.
Then according to the first condition, we have
[tex]\rm x + y = 90[/tex]
Then according to the second condition, we have
[tex]\rm y = 4x + 6[/tex]
It can be written as
[tex]\rm 4x - y = -6[/tex]
Then the equations are [tex]\rm x + y = 90[/tex] and [tex]\rm 4x - y = -6[/tex].
Thus, the correct option is B.
