Well, Y M C A With your arms
Let Joan's age be x and her sister's be y Then: x+y=27 and y=x-3 subsitute gives 2x-3=27 2x=30 x=15 (Joan is 15) Subsitute back 15+y=27 y=12 (sister is 12)
She is 56 years old and shes not dead yet.

Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
standard form (slope-intercept) is y = mx + b where m = slope and b = y intercept 6x + y = 12 subtract 6x from both sides y = -6x + 12 m = -6; b = 12
The equation is in standard form y = mx + b where m is the slope and b is the y-intercept. For y = 12x + 1, m = 12 so the slope is 12.
x equals -12 and y equals 1/4 of -12, so y = -3.
using normal algebraic methods, all I can get is m=0 and y=all numbers
12 = 24-y then y = 12
y = 12. It's the transitive property. y = 12 = 3x.
M=3 because y+y+y= 3xY and MY= MxY

Insufficient information. What is x when y = 12?
y-b/x=m
