Question

Here is a liner equation in two variables 2x + 4y - 31 = 123 determine whether each statement is true or false. the equation solved for x is x = 154 - 4y true or false ?

the equation solved for y is y = 77-x- 2 true or false ?

Answer 1

Both sentences are false.

Explanation:

Let's solve for x:

2x + 4y - 31 = 123

2x = 123 - 4y + 31

2x = 154 - 4y

x = 77 - 2y

Let's solve for y:

x = 77 - 2y

2y = 77 - x

y = 38.5 - 0.5x
