We need the following to be true
a+2b = -a
a+4 = 2a - 3b
Let's look at the first equation.
a + 2b = -a
Subtract both sides by a
2b = -2a
b = -a
Substitute b= -a into the second equation
a+4 = 2a + 3a
a + 4 = 5a
4a = 4
a = 1
Just take the negative of that and you get the value of b.
b = -1
Your solution is a=1 and b = -1.
Have an awesome day! :)
Answer:
3x - 2
Step-by-step explanation:
The answer is c i’m pretty sure
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...
42 + 37 = 79 Now we need to add the fractions
To add we need a
common denominator. 2 and 5 can both go into 10, so that will be a our common denominator.
Now you have...
which is equal to add that to the 79 we got earlier ...
The toal and final answer is
miles !Hope I helped and remember to vote this as the brainliest answer ! :)
