The steps that could be used to solve by substitution is:
6x + 2(−2x + 1) = 22
Substitution method--
The method of substitution states that from a equation the value of one variable is substituted in form of the other variable into the other equation.
From the first equation we have the value of y in terms of x as:
y = -2x + 1
Also, we have equation (2) as:
6x + 2y = 22
Hence, on putting the value of y we have:
6x+(-2x+1)=22
The answer is A
Because this where you gonna start your substitution
Answer:
64%
Step-by-step explanation:
25 - 9 = 16, so 16 of the games were won by Sally's team.
16/25 = 64% of the games were won
The simple solutions are:
Right 6: (-2+6,-3) = (4,3)
Left 6: (-2-6,-3) = (-8,-3)
Up 6: (-2,-3+6) = (-2, 3)
Down 6: (-2,-3-6) = (-2,-9)
Those are for horizontal or vertical
line segments.
, the coefficient of the x² term is 1.
