Simlify 10x-3y plus 2x-4y?
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
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
What is the answer to 2x-3y equals 4 y equals 8?
Since 2x-3y=4y=8 we can say that 4y=8 therefor y=2 We can also say that 2x-3y=4y and as y=2 2x-6=8 so 2x=14 and x =7 so y=2 and x=7
Solve this equation using subtitution 2x-3y equals 4 and x plus 4y equals -9?
2x-3y = 4 x+4y = -9 => x = -9-4y Substitute x = -9-4y into the top equation: 2(-9-4y)-3y = 4 -18-8y-3y = 4 -8y-3y = 4+18 -11y = 22 Divide both sides by -11 to find the value of y: y = -2 Substitute the value of y into the original equations to find the value of x: Therefore: x = -1 and y = -2 Remember that the product of a minus times a minus is equal to a plus when working out the original equations,
What is the x value 2x-3y equals -15 x equals 4y?
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
Simlify 10x-3y plus 2x-4y?
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
Use addition or substitution to find the value of x for this set of equations 2x - 3y equals -15 x equals 4y?
2x - 3y = -15x => -3y = -17x => -21y = -119x 2x - 3y = 4y => 2x = 7y => 21y = 6x so now you can add the two equations. 0 = -113x x=0 now plug back in 2*0 - 3y = -15*0 -3y = 0 y=0.
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
10x - 3y plus 2x - 4y?
10x+2x-3y-4y=12x-7y
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
Simplify the algebraic expression 4x plus 3y - 2x - 7y?
4x + 3y - 2x - 7y2x - 4y
What is the answer to 2x-3y equals 4 y equals 8?
Since 2x-3y=4y=8 we can say that 4y=8 therefor y=2 We can also say that 2x-3y=4y and as y=2 2x-6=8 so 2x=14 and x =7 so y=2 and x=7
Solve this equation using subtitution 2x-3y equals 4 and x plus 4y equals -9?
2x-3y = 4 x+4y = -9 => x = -9-4y Substitute x = -9-4y into the top equation: 2(-9-4y)-3y = 4 -18-8y-3y = 4 -8y-3y = 4+18 -11y = 22 Divide both sides by -11 to find the value of y: y = -2 Substitute the value of y into the original equations to find the value of x: Therefore: x = -1 and y = -2 Remember that the product of a minus times a minus is equal to a plus when working out the original equations,
How much is (2x plus 3y) plus (4x plus y)?
It is the same as: 6x+4y
If 2x 3y 17 and 3x 4y 24 then 5x 7y?
41
How simplify 5x plus 3y-2x plus 4y?
3x + 7y
