Answer:
...
Step-by-step explanation:
y is 1/3 x x + 7 so:
3 times x + (2 times 1/3x + 7) = 6
first, 1/3x plus 7 is 7 1/3x, so 7 1/3x x 2 is 14 2/3x.
14 2/3x + 3x = 17 2/3x
So no, it doesn't equal 6.
The equation is:
3 x x + 2(1/3 + 7) = 6
?
[tex]y = \frac{1}{3} x + 7 \\ \\ \\ 1. \: y = \frac{x}{3} + 7 \\ 2. \: y - 7 = \frac{x}{3} \\ 3. \: (y - 7) \times 3 = x \\ 4. \: 3(y - 7) = x \\ 5. \: x = 3(y - 7) \\ \\ \: or \\ \\ 1. \: \frac{1}{3} x + 7 = y \\ 2. \: \frac{1}{3} x = y - 7 \\ 3. \: \frac{ \frac{1}{3}x }{ \frac{1}{3} } = \frac{y - 7}{ \frac{1}{3} } \\ \\ answer. \: x = 3y - 21 \\ \\ \\ \\ 3x + 2y = 6 \\ \\ 1. \: 3x = 6 - 2y \\ 2. \: x = \frac{6 - 2y}{3} \\ 3. \: x = \frac{2(3 - y)}{3} \\ or \\ \\ 1. \: 3x = - 2y + 6 \\ 2. \: \frac{3x}{3} = \frac{ - 2y + 6}{3} \\ \\ answer. \: x = \frac{ - 2}{3} y + 2[/tex]
