Answer:
b = 10
Step-by-step explanation:
a) Solve by inspection. b=10 makes both fractions equal to 1.
Both the numerator and denominator of the fraction on the right are 2 greater than those of the fraction on the left. The fractions will be equal when numerator and denominator are equal.
__
b) Multiply by 60 and solve in the usual way.
6b = 5(b+2)
b = 10 . . . . . . . . . . subtract 5b
__
c) Expand the fraction on the right, subtract the variable term.
b/10 = b/12 + 2/12
b(1/10 - 1/12) = 1/6
b/60 = 1/6 . . . . simplify
b = 60/6 = 10 . . . . multiply by 60

There is no "y", so you cannot solve for y. This is another example of poor quality control (editing) of math curriculum materials. It is my sincere wish that you not have to put up with that. Math is tough enough without this added confusion.
Answer: -1
Step-by-step explanation:
4x-3x= 4-5
x= -1
Answer:
y = -2x - 1
Step-by-step explanation:
pt slope formula is
y-y₁=m(x-x₁)
First put values in
y--5=m(x-2) (you could used either point, I chose the first one out of the two)
Then find the slope
-1+5/0-2
4/-2
-2
y+5=-2(x-2)
solve
y+5=-2x+4
y=-2x-1
