Question

Which variable would it be easiest to solve for

Answer 1

Answer: the easiest to solve for is y in the second equation.

Explanation: To solve for the y in the second equation, only one step is needed, namely subtracting 3x from both sides:

3x + y = 9

y = 9 - 3x

This is unlike the rest of the options, which require at least two operations.

Answer 2

Answer is :Y is the easiest first using second equation . Ill show you steps below why . If you want to see the steps .

2x+4y=26

3x+y = 9

So first solve second equation

3x+y=9

Y= -3x+9

Now plug into first equation

2x+4y=26

2x+4(-3x+9)=26

2x-12x+36=26

-10x+36=26

-10x= 26-36

-10x= -10

X=1

So now solve for y in second equation

Y= -3x+9

Y= -3(1)+9

Y= -3+9

Y= 6

So if you were to be asked answer in point (1,6).
