What else can I help you with?
2x - 3y equals 4 and x plus 4y equals -9?
(-1,-2)
2x plus 3y equals 13 x -y equals 9?
x = 8, y = -1
If x equals 2 and y equals 9 then 7x plus 3y equals?
7x+3y where x=2 and y=9 can be written as (7*2)+(3*9) which can be simplified to (14)+(27), from there it's basic addition.
What is the solution of x plus y equals -2 and 2x plus 3y equals -9?
x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5
What does y equal for this x-3y plus 9 equals 0?
x-3y+9=0 So x+9=3y So x/3+3=y That means y= x/3+3 Of course you still don't know what y is, except in terms of x.
What is 4x plus 3y equals 9?
4x + 3y=9 x=0 y=3
2x - 3y equals 4 and x plus 4y equals -9?
(-1,-2)
2x plus 3y equals 13 x -y equals 9?
x = 8, y = -1
What is 4x plus 3y plus x equals?
5x+3y
If x equals 2 and y equals 9 then 7x plus 3y equals?
7x+3y where x=2 and y=9 can be written as (7*2)+(3*9) which can be simplified to (14)+(27), from there it's basic addition.
What is the answer to x-3y plus 3z equals -4 2x plus 3y-z equals 15 4-3y-z equals 19?
4.34684352143
What is x and y in 3x plus 3y equals 17.7 and 2x plus 3y equals 15.55?
x = 2.15 and y = 3.75
What is the solution of x plus y equals -2 and 2x plus 3y equals -9?
x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5
Sketch the solution of 4x plus 3y -9 and x -3?
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
What does y equal for this x-3y plus 9 equals 0?
x-3y+9=0 So x+9=3y So x/3+3=y That means y= x/3+3 Of course you still don't know what y is, except in terms of x.
How do you solve x plus 3y equals 2?
x+3y=2 x= -5 y = 1
X plus 3y equals 4 -x plus 2y equals -4?
x + 3y = 4 -x + 2y = -4 Simultan eous eq'ns. Eliminate 'x' by adding. 4 Hence 5y = 0 y = 0 When y = 0 Substitute x + 3(0) = 4 x + 0 = 4 x = 4 So the answer as a coordinate pairs is ( x,y) = ( 4,0)
