4x + 3y - 2x - 7y2x - 4y
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
-7y + 4y = -3y
2x - 3y = -4x + 4y = -9from the second equation x = -9-4y , substitute it in the first equation.2(-9-4y)- 3y= -4-18-8y-3y = -4-18-11y = -4-11y = -4+18-11y = 14y = -14/11now, solve for x :x = -9-4yx = -9-4(-14/11)x = -43/11
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
It is the same as: 6x+4y
4x + 3y - 2x - 7y2x - 4y
3x + 7y
6x - 4y
6x plus 4y
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
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!
