I REALLY NEED HELP WITH THIS QUESTION

$1.75

Step-by-step explanation:

4b+n=12;2b+3n=18.5

Step: Solve4b+n=12for n:

4b+n+−4b=12+−4b(Add -4b to both sides)

n=−4b+12

Step: Substitute−4b+12fornin2b+3n=18.5:

2b+3n=18.5

2b+3(−4b+12)=18.5

−10b+36=18.5(Simplify both sides of the equation)

−10b+36+−36=18.5+−36(Add -36 to both sides)

−10b=−17.5

(Divide both sides by -10)

b=1.75

Step: Substitute1.75forbinn=−4b+12:

n=−4b+12

n=(−4)(1.75)+12

n=5(Simplify both sides of the equation)

b=1.75 and n=5

 2x+3y=12 becomes

3x+2y=-8  becomes  

Step-by-step explanation:  Slope intercept form is y = mx + b

m is the slope. b is the y-intercept.

2x + 3y = 12  Subtract 2x from both sides

3y = -2x + 12 .   Divide both sides by 3

y = -2x/3 + 4   to clarify the slope as a fraction it is

3x + 2y = -8  subtract 3x from both sides

2y = -3x - 8   divide both sides by 2

y = -3x/2 - 4 .  to clarify the slope as a fraction
