Answer: the answer would be 20



Step-by-step explanation: The answer 20 is from 1400 divided by 70 making 20, if you take 1400 and turn it into 14 then 70 into 7 then divide 14 by 7 you get 2 now just add a zero to your answer.

3x - 7y = 11<br> What is y equal to?
lara31 [8.8K]

Answer:

3.666666667

Step-by-step explanation:

Simplifying

3x + -7y = 11

Solving

3x + -7y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

3x + -7y + 7y = 11 + 7y

Combine like terms: -7y + 7y = 0

3x + 0 = 11 + 7y

3x = 11 + 7y

Divide each side by '3'.

x = 3.666666667 + 2.333333333y
