Answer:

A

Step-by-step explanation:

Equation: $4x+4y=20$

The slope-intercept form is:

$y=mx+b$

So, in the equation given:

$4x+4y=20$

$4y=20-4x$

Divide both sides by 4

$y=5-x$

Slope-intercept form:

$y=-x+5$

Solve each system by substitution 2x + y = 20 and 6x - 5y = 12

$\huge\mathbf{Answer࿐}$

$\underline{ \underline{ \bf{step} - 1}}$

Taking first equation,

$2x + y = 20$

$y = 20 - 2x$

$\underline{ \underline{ \bf{step} - 2}}$

plugging the value of y in second equation,

$6x - 5y = 12$

$6x - 5(20 - 2x) = 12$

$6x - 100 + 10x = 12$

$16x = 12 + 100$

$x = \dfrac{112}{16}$

$x = 7$

$\underline{ \underline{ \bf{step} -3}}$

plugging the value of x in first equation,

$2x + y = 20$

$(2 \times 7) + y = 20$

$14 + y = 20$

$y = 20 - 14$

$y = 6$

<h2>Conclusion :</h2>

$x = 7$
$y = 6$
