First, you want all the variables to be on one side:
a - 3b = 4
a - b = -2
Now you want to eliminate one of the variables, in this case a is easiest.
Subtract the second equation from the first and you're left with:
-2b = 6
so b = -3
Sub the value of b back into either of the equations and solve for x:
a - (-3) = -2
a = -5
So your answer is (-5,-3)
Answer:
50 miles per hour
Step-by-step explanation:
To find rate, we use the rate formula:
r = rate, d = distance and t = time
Plug in distance and time using the numbers provided:
now to find rate we only need to divide 130 by 2.6 to get r = 50.
