Okay the first one is what u did lol
Answer:
k + a = 62
k = 31 + a
Step-by-step explanation:
Given that:
Sum of ken and Alan's age = 62
Ken is 31 years older than Alan
k + a = 62 - - - (1)
k = 31 + a - - - (2)
Hence, the system of equation which best describes the ages of Ken and Alan are:
k + a = 62
k = 31 + a
Socratic and mathaway are both great to use with schoolwork and homework

Answer:
one solution; (x, y) = (4/3, 11/3)
Step-by-step explanation:
The two lines described by the equations have different slopes, so there will be exactly one solution to the system of equations.
__
The slope of the line will be the coefficient of x when you solve for y. In the first equation, the slope is 2. In the second equation, you can solve for y by adding x, and dividing by 2. Then the slope of that line is found to be 1/2.
Lines with different slopes must intersect somewhere. That point of intersection is the (one) solution to the system of equations.
