Y equals -3x plus 1?
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2
How do you solve 4x-2y equals 10?
You need more information to solve for x and y. One answer is x=3 and y=1.
What is the answer and steps for x plus y equals 1 2x-y equals -2 in the substitution method?
To solve the system of equations using the substitution method: Solve one of the equations for a variable (e.g., x) in terms of the other variable (e.g., y). From the first equation, x = 1 - y. Substitute the expression for x into the second equation. Replace x in the second equation with (1 - y), giving 2(1 - y) - y = -2. Simplify and solve for y. Expanding and rearranging, we get 2 - 2y - y = -2. Combining like terms, -3y = -4, so y = 4/3. Substitute the value of y back into the first equation to solve for x. x = 1 - (4/3) = 3/3 - 4/3 = -1/3. Therefore, the solution to the system of equations is x = -1/3 and y = 4/3.
What is the inverse of y equals 3X3?
Since the equation is in terms of x, you need to switch the x's and y's, and then solve it for y again. y=3x^3 --> x=3y^3 --> y=(x/3)^(1/3)
How do you solve x plus y equals 4 and y equals 2X plus 1 by substitution method?
If: x+y = 4 and y = 2x+1 Then: 4-x = 2x+1 => 3 = 3x => 1 = x So by substitution: x = 1 and y = 3
y=3x+3 solve for y?
y=3(x+1)
Y equals -3x plus 1?
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2

Solve and graph y equals 3 plus x?
The given equation y=3+x is a linear line with the slope of 1 and y-intercept of 3.
How do you solve y equals x-1 x plus y equals 3 using subsution?
y= x-1y= 3Since y equals 3, you can replace any "y" you see with a three.3= x-1Move the one to the other side.3+1 = x -1 +14=x(you already knew y=3)
What is the answer to y equals -4x-3?
-1
The vertex of this parabola is at (-2, -3) When the x-value is -1, the?
Y=a(x-h)+k is the vertex formula. Since the vertex is at (-2,-3) this parabola has the equation: y=a(x+2)^2-3 We can plug in x=-1 but we really need to know a, to solve for y. ( we can solve it, but we will have an a in the solution)
Use the graph to solve the system of linear equations x - y=4 4x + y=1?
x=4+y 4x+y=1 = 4(4+y)+y=1 16+4y+y=1 16+5y=1 5y=-15 y=-3 x=4+y = x=4+(-3) x=1
