Determine whether the equation 3(4g+6)=2(6g+9) has one solution, no solution, or infinitely many solutions. The equation has . Q

taurus [48]

So firstly, foil 3(4g + 6) and 2 (6g + 9): $12g+18=12g+18$

Now since the quantity is the same on both sides of this equation, this means that <u>this equation has infinite solutions.</u>

Anyone know the answer ?

Answer: see where the two lines intercept and when you get the answer, look to see which region is is the closest to the answer but if you look closer region A is closer plus open/Search a graph and put y>-x in the first box and put y<x-2 in second box to see where is intercept at the you get your answer, but region A is the answer you do need.

Use substitution to solve the following system of equations. What is the value of y? {3x+2y=12{5x−y=7 A) y = -3B) y = 3C) y = -2

Vlad [161]

<em>Answer</em>

B) y = 3

<em>Step-by-step explanation</em>

Given the system of equations:

$\begin{gathered} 3x+2y=12\text{ \lparen eq. 1\rparen} \\ 5x-y=7\text{ \lparen eq. 2\rparen} \end{gathered}$

Isolating x from equation 1:

$\begin{gathered} 3x+2y-2y=12-2y \\ 3x=12-2y \\ \frac{3x}{3}=\frac{12-2y}{3} \\ x=\frac{12}{3}-\frac{2}{3}y \\ x=4-\frac{2}{3}y\text{ \lparen eq. 3\rparen} \end{gathered}$

Substituting equation 3 into equation 2 and solving for y:

$\begin{gathered} 5(4-\frac{2}{3}y)-y=7 \\ 5\cdot4-5\cdot\frac{2}{3}y-y=7 \\ 20-\frac{10}{3}y-y=7 \\ 20-\frac{13}{3}y=7 \\ 20-\frac{13}{3}y-20=7-20 \\ -\frac{13}{3}y=-13 \\ (-\frac{3}{13})\cdot-\frac{13}{3}y=(-\frac{3}{13})\cdot-13 \\ y=3 \end{gathered}$
