I'm marking good anwsers as brainliest. When solving this system of equations with substitution one of the following is a step. x+y=6, - 6x+8y = 6 -6(-x + 6) + 8y = 6 x+y = 6 -6x+8 (-x + 6) = 6 8y = 6x + 6

Ответ:
(C)![-6x+8(-x+6) = 6](/tpl/images/0711/8786/41bab.png)
Step-by-step explanation:
Given the system of equations
From the first equation:
x+y=6
Making y the subject, we have:
y=-x+6
Substituting y=-x+6 into the second equation, we obtain:
The correct option is C.
NOTE: The goal of substitution is to reduce the number of unknown variables to 1. Therefore, after the substitution, if you still have the two unknown, you might have done something incorrect.
Ответ:
y = -8x + 2
Step-by-step explanation:
A slope-intercept form equation is y = mx + b where m is the slope and b is the y-intercept. Using this, we can plug in -8 and 2 to create our equation.
