10x plus 2y plus 8z-5x plus 4z-4y equals?
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is the slope and y intercept of the equation 5x plus 4y equals 20?
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
X plus 2y equals -1 5x - 4y equals 16?
x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5
Slope of 5x plus 4y equals 20?
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y

What is the slope of the equation 5x plus 4y equals negative 3?
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
5x plus 4y equals 11 what is the value of y when x equals -1?

5x plus 4y equals 12 7x - 6y equals 40?
(4, -2)
10x plus 2y plus 8z-5x plus 4z-4y equals?
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
5x - y equals 27 5x plus 4y equals 42?
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is the slope and y intercept of the equation 5x plus 4y equals 20?
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
5x-4y equals -41 4x plus 35 equals?
5x - 4y = -41 => 5x = 4y - 41 => x = (4y - 41)/5 Then 4x + 35 = 4*[(4y - 41)/5] + 35 = 16y/5 - 164/5 + 35 = 16y/5 -11/5 or (16y - 11)/5
