What is x y 3 and 3x - 4y - 19 solve using substitution?
2x-y=3 2/3x-y=-1
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
-3x-y equals 3 and -3x-5y equals -21 please help me solve the above equation through the substitution method.?
-3x = 3 + y 3 + y - 5y = -21 -4y = -24 y = 6 x = -3
Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
Solve by substitution y equals -4x - 7 and y equals 3x?
The easiest way to solve this system of equations is to solve for a variable in one of the equations. In the second equation, y = 3x. This can be substituted into the first equation: y = -4x - 7; 3x = = -4x - 7; 7x = -7; x = -1. Since we have determined that x equals -1, we can then substitute -1 into either equation to find our corresponding y-value. Thus: y = 3x; y = 3(-1) y = -3. Thus, the solution to this system of equations is (-1, -3).
What is x y 3 and 3x - 4y - 19 solve using substitution?
2x-y=3 2/3x-y=-1
How do you solve 3x-3y9 Y-3x-3 by substitution method?
If you mean: 3x-3y = 9 and y-3x = -3 then by adding both equations y = -3 and by substitution x = 0
What is the solution to y3x 22 y2x 16 by using systems by substitution?
If you mean (1) y + 3x = 22 and (2) y + 2x = 16, then (1) y = 22 - 3x (sub this into (2)) (2) (22 - 3x) + 2x = 16 -x = -6 x = 6 y = 22 - 3x = 22 -3(6) = 4 solution: (6,4)
How do you solve the system of equation by substitution x plus 2y-2 3x plus 4y6?
If you mean x+2y = -2 and 3x+4y = 6 then by solving the simultaneous equations by substitution x = 10 and y = -6
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
How do you solve systems by using the substitution method?
You solve one of the equation for one of the variables. For example, if the variables involved are "x" and "y", you might solve for "y". It doesn't really matter what variable you solve for first, so you can solve for whatever variable is easiest to solve. Then - assuming you got, for example, "y = 3x -1", in this example you would replace every "y" by "3x - 1" in the other equation or equations.
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24?
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
Solve this equation using substitution 3x plus 2y equals 2 and -2 plus y equals 8?
From second equation: y = 8 + 2xSubstitute for y in first equation: 3x + 16 + 4x = 2ie 7x = -14ie x = -2 and y = 4
Solve this equation using substitution 5x plus y equals 5 and 3x plus 2y equals 3?
From first equation: y = 5 - 5xSubstitute for y in second equation: 3x + 10 - 10x = 3ie -7x = -7ie x = 1 and y = 0
Solve this equation using substitution 5x plus y equals 1 and 3x plus 2y plus 2?
It is not possible to do so because the question contains one equation (5x + y = 1) and one expression (3x + 2y + 2). An expression cannot be solved.
What is the answer for the ordered pair form x plus 7y equals 39 3x minus 2y equals 2 using substitution?
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
Solve by substitution 3x plus 2y equals 6 4x-y equals 2?
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
