What is the answer to y equals 3x 3x plus 4y equals 30?
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
What does -x plus 4y-3x equals?

What is the slope of the line 3x plus 4y 12?
If you mean: 3x+4y = 12 then y = -3/4x+3 whereas -3/4 or -0.75 is the slope and 3 is the y intercept
Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?
7(3y-2)-(-4y+9)
What is the slope of a line that is perpendicular to the line represented by the equation 3x plus 4y equals 12?
4/3 First, get this into slope-intercept form (get y by itself). 3x+4y=12 -> Move 3x to the right by subtracting from both sides. -3x -3x 4y=12-3x -> get y alone by dividing everything by 4. 4y=-3x+12 ÷4 ÷4 ÷4 y=(-3/4)x+3 -> The slope is -3/4. To get the perpendicular line's slope you take the slope (-3/4) and flip it and switch the sign: negative becomes positive, 3/4 becomes 4/3.
What is the slope to 3x plus 4y equals 12?
3x + 4y = 12 Subtract 3x from each side 4y = 12 - 3x Divide by 4 on each side y = 3 - .75x The slope is what is multiplied by "x" or -.75
Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
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 slope of a line perpendicular to the line whose equation is 3x plus 4y equals 12?
4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3
What is the slope of a line that is parallel to the line represented by the equation 3x plus 4y equals 12?
q2
What does 3x-4y equals 12 equal?
3x-4x=12 that means -x equals 12 so x equals -12
How do you rewrite -3X plus 4Y equals 11?
4y = 3x+11 or as y = 3/4x+11/4
What is the solution of this system 3x plus 4y equals 5 x-4y equals 7?
Add the two equations and get 4x = 12 so x = 3 and y = -1
3x plus 2y equals 7 and 2x plus 4y equals 18?
(-1, 5)
3x plus 2y equals 7 2x plus 4y equals 18?
(-1, 5)
3x plus 4y equals 7 2x plus y equals 3?
