What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
What is the value of (5x plus 2y plus 19) plus (9y plus 7x-10)?
It is 12x + 11y + 9.
What is the ordered pair for 9x-2y equals 73 5x-9y equals 9?
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)
What is y if 5y equals 2y plus 9?
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
9y plus 5 equals 0 what is y?
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
What is the solution for 2y-5 equals 11y plus 40?
2y-5=11y+40 Subtract 2y from both sides -5=9y+40 Subtract 40 from both sides. -45=9y Divide by 9. -5=y
What is the value of (5x plus 2y plus 19) plus (9y plus 7x-10)?
It is 12x + 11y + 9.
What is the ordered pair for 9x-2y equals 73 5x-9y equals 9?
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)
What is the slope-intercept form of 9 plus 9y equals 27x?
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
What is 5y equals 9 plus 2y equals?
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
What is y if 5y equals 2y plus 9?
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
9y plus 5 equals 0 what is y?
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
2y plus 3 equals 3y plus 9?
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
