In order to factor this, we will need to take something out to get it to factor. Lets take out a greatest common factor, in this case our greatest common factor will be 3.
We will then write it as:
-3(5t+2)
Re-write
8x + 14y = 4 (1)
-6x - 7y = -10 (2)
multiply (1) by 3 and (2) by 4
now you have
24x + 42y = 12
-24x - 28y = -40
-------------------------add
14y = -28
y = -2
8x + 14y = 4
8x + 14(-2) = 4
8x - 28 = 4
8x = 32
x = 4
answer
x = 4 and y= -2

Step-by-step explanation:
Answer:
Subsitution/Elimination method
Step-by-step explanation:
There are many ways , it all depends on your question. For example, first look at your equation and see if you can simplify the equation to make it easier. Then I recommend using the subsituition or elimination method because it is easy.
Yes you are doing it right because 7*5=35 and 8*3=24.
