How do you solve -8x plus 4y equals 28 for y?
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
Solve this equation using subtitution 8x subtract y equals 31 and 5x plus 3y equals 23?
8x - y = 31 <=> y = 8x - 31. 5x + 3y = 23 => 5x + 3 * (8x - 31) = 23 <=> 5x + 24x - 93 = 23 <=> 29x = 23 + 93 <=> 29x = 116 <=> 29x/29 = 116/29 <=> x = 4. y = 8x - 31 => y = 8 * 4 - 31 <=> y = 32 - 31 <=> y = 1.
How do you solve 2x plus 4y0 when y-8x?
Without any equality signs the given expression is not an equation and so therefore any solutions are not possible.
Solve this equation using addition method -8x plus 3y equals -5 and 8x subtract 2y equals 6?
x=1, y=1
How do you solve 8x plus 20y equals -80?
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
Solve 4x plus 3y equals 8x plus y for y?
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
How do you solve -8x plus 4y equals 28 for y?
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
What is the answer to 2y10-x?
(y - 2)(2y + 5)
How can you solve Slope8y-intercept-3?
If you mean slope 8 and y intercept 3 then the equation is y = 8x+3
Solve this equation using subtitution 8x subtract y equals 31 and 5x plus 3y equals 23?
8x - y = 31 <=> y = 8x - 31. 5x + 3y = 23 => 5x + 3 * (8x - 31) = 23 <=> 5x + 24x - 93 = 23 <=> 29x = 23 + 93 <=> 29x = 116 <=> 29x/29 = 116/29 <=> x = 4. y = 8x - 31 => y = 8 * 4 - 31 <=> y = 32 - 31 <=> y = 1.
How do you solve 2x plus 4y0 when y-8x?
Without any equality signs the given expression is not an equation and so therefore any solutions are not possible.
Solve this equation using addition method -8x plus 3y equals -5 and 8x subtract 2y equals 6?
x=1, y=1
How do you solve 8x plus 20y equals -80?
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
For 5x-2y10 what is the y intercept?
If you mean: 5x -2y = 10 then y = 2.5x -5 whereas -5 is the y intercept and 2.5 is the slope
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
8x-7y equals 42 and 24x plus y equals 170 what is x and y?
8x-7y=42 24x+y=170 An easy way to begin is to solve for one variable in one of your two equations. I will use the second equation to solve for y: 24x+y=170 y=170-24x This solution for y will then be plugged into the first equation so the equation will be of one variable, and therefore solvable: 8x-7y=42 8x-7(170-24x)=42 8x-1190+168x=42 176x=1232 x=1232/176=7 x=7 The solution we made for y can now be used with the solved value of x to find y's numerical value. y=170-24x y=170-24(7) y=170-168 y=2 So, finally, we get that x=7 and y=2
