Answer:

(1, 5)

Step-by-step explanation:

Substitution works well here. Solving the second equation for x, we get x = y - 4. Substituting y - 4 for x in the first equation results in

-3(y - 4) + y = 2.

Next, we perform the indicated multiplication and obtain:

-3y + 12 + y = 2, or -2y = -10

Dividing both sides by -2 yields y = 5. As seen above, x = y - 4; if y = 5, then x = 5 - 4 = 1.

The solution is (1, 5)

The graph of x = 2(y-4) and x = 5(y-4) are shown below answer my following question to receive brainlest!!!

Ivanshal [37]

Answer:

The graph $x = 2(y - 4)$ has a greater slope than the graph of $x = 5(y - 4)$ .

Step-by-step explanation:

$x = 2(y - 4)\\\frac{x}{-2y} = \frac{-2y}{-2y} - 4\\-2y \frac{x}{-x} = \frac{-4}{-x} \\\frac{-2y}{-2} = \frac{-1x}{-2} \frac{-4}{-2}\\y = \frac{1}{2}x + 8$ $x = 5(y - 4)\\\frac{x}{-5y} = \frac{5y}{-5y} - 20\\\frac{x}{-x} - 5y = \frac{-20}{-x}\\\frac{-5y}{-5} = \frac{-1x}{-5} \frac{-20}{-5}\\y = \frac{1}{5}x + 4$
