9Y + 4 = 2Y + 25
subtract 2Y from both sides
7Y + 4 = 25
subtract 4 from both sides
7Y = 21
divide both sides integers by 7
(7/7)Y = 21/7
Y = 3

-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
X-2y equals o 9y-4x equals 1 substitution method?
x - 2y=0 so x = 2y 9y - 4x=1 Substituting for x, 9y-4*(2y) = 1 or 9y-8y = 1 so that y = 1 then x = 2y = 2*1 = 2
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+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
How do you factor 3x squared plus 25xy-18 squared?
If that's -18y2, the answer is (3x - 2y)(x + 9y)
9y-3y plus 2y equals?
9y-3y=6y; 6y+2y=8y; so your answer is 8y
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
10y equals 2y plus 4 plus 7y?
10y = 9y + 4, so y = 4
X-2y equals o 9y-4x equals 1 substitution method?
x - 2y=0 so x = 2y 9y - 4x=1 Substituting for x, 9y-4*(2y) = 1 or 9y-8y = 1 so that y = 1 then x = 2y = 2*1 = 2
2y plus 9y plus 9 equals?
well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+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
How do you factor 2y squared minus 9y plus ten?
(2y - 5)(y - 2)
Subtract 4y cubed plus 2y squared plus y from 5y cubed - y?
9y cubed plus 2y squared
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
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
If x equals 5 and y equals 2 then 5x plus 9y equals?
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
