X plus 7y equals 12 3x - 5y equals 10?
(5, 1)
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
What is the order pair for x plus 7y equals 33 and 3x - 2y equals 7?
The ordered pair is (5, 4).
Factor 21-7y plus 3x-xy?
21-7y+3x-xy7(3-y)+x(3-y)
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
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
Solve 3X plus 7Y equals 14 for Y?
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
X plus 7y equals 12 3x - 5y equals 10?

Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
If T equals 3x plus 7y what is T when x equals 4 and y equals 6?
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
8x plus 7y equals 37 2y equals 4x - 2?
no its not a solution
What is 3x plus 5y equals 44 and 8x-7y equals -25 in odered pair?
(3,7)
What is th y intercept of 7y plus 3x-21 equals 0?
3
What is the slope of -7y plus 21 equals 3x?
-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
