Which is a solution to the equation 5x plus 2y equals 9?
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
What is y if -6y - 9 equals 5y plus 24?
-6y - 9 = 5y + 24Add 6y to each side of the equation:-9 = 11y + 24Subtract 24 from each side:-33 = 11yDivide each side by 11:-3 = y
What is y when 2y plus 10 equals 28?
2Y + 10 = 28 subtract 10 from both sides 2Y + 10 - 10 = 28 - 10 2Y = 18 divide both sides by 2 Y = 9 -------- check 2(9) + 10 = 28 18 + 10 = 28 28 = 28 checks
Find slope for 5y equals 160 plus 9x?
First write it out. 5y=9x+160 To get it into slope form, it must become the form y=mx+b. In other words, y must be by itself, so you divide every number by 5. It becomes: y=9/5x+32. So the slope is 9/5.
What is the x- value of x-2y plus z equals -9 3y-2z equals 4 2x plus y plus 5z equals -5?
x-(x-2y)+z=-9 3y-2z=4 2x+y+5z=-5 x-(x-2y)+z=-9 --distribute negative through bracket--> x-x+2y+z=-9 x-x+2y+z=-9 --combine like terms (x)--> 2y+z=-9 2y+z=-9 --isolate z--> z=-9-2y substitute z into second equation: 3y-2(-9-2y)=4 --multiply -2 through bracket--> 3y+18+4y=4 3y+18+4y=4 --subtract 18 from both sides--> 3y+4y=-14 3y+4y=-14 --combine like terms--> 7y=-14 7y=-14 --divide both sides by 7--> y=-2 Substitute value of y into simplified first equation: z=-9-2(-2) --multiply through the bracket--> z=-9+4 z=-9+4 --combine like terms--> z=-5 Substitute values of y and z into third equation: 2x+(-2)+5(-5)=-5 --multiply through brackets--> 2x-2-25=-5 2x-2-25=-5 --combine like terms--> 2x-27=-5 2x-27=-5 --add 27 to both sides--> 2x=22 2x=22 --divide both sides by 2--> x=11 x=11, y=-2, z=-5
What is y if 5y equals 2y plus 9?
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
5y plus 4 - 2y equals 9?
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
Solve 3y-9 equals -2y plus 4?
Add 2y - 4 to each side; 5y - 13 = 0 so y = 2.6
What is 7y-8 equals 2y plus 37?
It's a simple linear equation in 'y'.To find the solution:7y - 8 = 2y + 37Subtract 2y from each side of the equation:5y - 8 = 37Add 8 to each side:5y = 45Divide each side by 5:y = 9
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
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
What is the value of y if 3y is a solution to the equation 5y-3y equals 18?
5y - 3y = 18 2y = 18 y = 18/2 y = 9
What is the slope-intercept form of 3x plus 2y equals 9?
3x+2y=9 2y=9-3x y=-1.5x-4.5
4x plus 5y equals 2 7x minus 2y equals 1 solve by substitution?
4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43
2y plus 9 equals 17 can be called?
