Answer:
C
Step-by-step explanation:
Use elimination by multiplying thw whole top equation by 2. (both sides)
then cancel out y and solve for x. plug back in to get y

Step-by-step explanation:
3 - 2(b - 2) = 2 - 7b
To solve this first distribute -2 to (b - 2)
3 + (-2b + (-2) x -2) = 2 - 7b
when we simplify this it becomes:
3 + (-2b + 4) = 2 - 7b
We take (-2b + 4) out of the parenthesis:
3 - 2b + 4 = 2 - 7b
Now simplify again.
7 - 2b = 2 - 7b
Now send all the b's to one side and constants on the other.
7 - 2 = -7b +2b
5 = 5b
b = 1
When solving a system of linear equations by graphinh, we graph both of those equations in the same coordinate system. The solution to the system is gonna be in the point where the two lines cross.
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Hi there!
If any term, no matter what the number multiplied by zero will always turn out to be zero. I can give you an example of why this is correct.
We'll use apples. :P
If we have four apples multiplied by zero, you'd have zero apple because there's NO groups of apples to use.
Two times three is six because there are two groups of three, or three groups of two. But since earlier we said that there were zero groups of apples, there is zero groups of four so that cancels out to make none.
Hope this helps! :D
