Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
<span>-ay=-bx+2 </span>
<span>ax+by=3 </span>
<span>Divide each term in the equation by -1a. </span>
<span>y=(bx-2)/(a) </span>
<span>ax+by=3 </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>y=(bx)/(a)-(2)/(a) </span>
<span>ax+by=3 </span>
<span>The equation is not linear, so the slope does not exist. </span>

Answer:
x = -3, 6
Step-by-step explanation:
First, add 18 to both sides
x² - 3x - 18 = 0
+ 18 + 18
x² - 3x = 18
Add 9/4 to both sides because that is the square of half of -3
x² - 3x + 9/4 = 18 + 9/4
Multiply both sides by 4 to get rid of the fractions
(x² - 3x + 9/4 = 18 + 9/4)4
4x² - 12x + 9 = 72 + 9 = 81
Factor the left side of the equation
(2x - 3)² = 81
√(2x - 3)² = √81
Because of the square root, this will result in a positive number and a negative number
2x - 3 = 9
2x - 3 = -9
For both equations, add 3 to both sides then divide by 2
2x - 3 = 9
+ 3 +3
2x = 12
2x/2 = 12/2
x = 6
2x - 3 = -9
+ 3 + 3
2x = -6
x = -3
To find the number of possible combinations, you multiple the possible number of outcomes for each category together. For example, there are 5 choices of pastries, 4 choices of drinks, and 2 newspaper choices, so normally there are 5 x 4 x 2=40 possible combinations. Without a muffin, these numbers would change to 4 x 4 x 2=32. The difference would be 8 possible options, so choice C.
