Subtract 9 from both sides
b = -12 - 9
simplify -12 - 9
Answer: b = -21
9 + -21 = -12 is true.
simplify brackets
simplify q + -9 to q - 9
add 9 to both sides
simplify 12 + 9 to 21
q = 21
21 + -9 = 12 is true.

Answer:
See below.
Step-by-step explanation:
2a. E = 8.25h + 1.2n
2b. E = 8.25 * 3.5 + 1.2 * 10 = $40.88
2c. 8.25 * 8 + 1.2n = 91.2
66 + 1.2n = 91.2
1.2n = 25.2
n = 21 magazines.
set them equal to each other
x²+1=x+1
minus 1 from both sides
x²=x
minus x both sides
x²-x=0
factor
x(x-1)=0
set each to 0
x=0
x-1=0
x=1
subsitute back to find y values
y=x+1, y=0+1, y=1, one point is (0,1)
y=x+1, y=1+1, y=2, another point is (1,2)
the 2 points of intersection are (0,1) and (1,2)
