if:
2x + 6 = -6
then:
2x = -12
x = -6
if:
5x + 7y = 1
then:
5(-6) + 7y = 1
7y = 31
y = 31/7

2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
Let's simplify this together, friend. First, we add the terms with 'x' together: 2x - 5x = -3x. Then, we add the terms with 'y' together: 4y + 3y = 7y. So, the expression simplifies to -3x + 7y. Remember, there are no mistakes, just happy little accidents in math!
