Answer:
n=-9
Step-by-step explanation:
Solution for -8-5n=64+3n equation: Simplifying -8 + -5n = 64 + 3n Solving -8 + -5n = 64 + 3n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3n' to each side of the equation. -8 + -5n + -3n = 64 + 3n + -3n Combine like terms: -5n + -3n = -8n -8 + -8n = 64 + 3n + -3n Combine like terms: 3n + -3n = 0 -8 + -8n = 64 + 0 -8 + -8n = 64 Add '8' to each side of the equation. -8 + 8 + -8n = 64 + 8 Combine like terms: -8 + 8 = 0 0 + -8n = 64 + 8
This would be the identity property of addition
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14
7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7
if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions
You didn’t write the question and thanks for the point
