8y-7x

It is 16y+23x simplified

2y + 7x + y-1?

-7x - 2y = -3

3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y

4x + 8 + 7x + 12 = 11x + 20

The answer to the math problem of 5x plus 7x-4x 6 is -12.

Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x

56xy + 2y + 3x

4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2

-4x

As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.

4x-5.

The standard form is 7x + 2y - 3 = 0

4x+5=7x-8 the ansewr is 3.25

3x + 4x = 7x

3x + (-2 + 4x) = -2 + 7x

5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y

4x + 2y = 12 3x - 2y = 9 Have to use simultaneous equations, so add together to get : 7x = 21 so x = 3 Put it into any part of the equation 4x3 + 2y = 12 12 + 2y = 12 2y = 0 y = 0, x = 3

(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y

Subtract by 7x and divide by 2.
