What is 6y equals -42?
48
5x - y equals 27 5x plus 4y equals 42?
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
If T equals 3x plus 7y what is T when x equals 4 and y equals 6?
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
What is the y intercept of the line y equals 8x plus 7?
7 is the y intercept
What is the value of x and y in x plus y equals -7 x-y equals 1?
-6

How do you solve the quadratic equation 42 equals y2-y by factoring?
Rewrite equation as: y2-y-42=0 So you need two numbers that: multiply to -42 and add to -1 Those two numbers are: -7 and 6 so to factor you get: (y-7)(y+6)=0 y=7 y=-6
Find y if y equals -42?
If y=-42,theny = -42.QED? ? ?============Another answer:THERE it is ===> Y = -42
What is 192-y equals 150?
192-y equals 150 = 42
What is the answer to y equals 2x plus 4 when x equals 42?
Given y = 2x + 4, plug in x = 42 and simplify: y = 2(42) + 4 y = 84 + 4 y = 88
-42 plus y equals -71?
-113
What is 49 - 7 equals?
42
How do you factor y²-y-42?
y2 -y -42 = (y+6)(y-7) when factored
8x-7y equals 42 and 24x plus y equals 170 what is x and y?
8x-7y=42 24x+y=170 An easy way to begin is to solve for one variable in one of your two equations. I will use the second equation to solve for y: 24x+y=170 y=170-24x This solution for y will then be plugged into the first equation so the equation will be of one variable, and therefore solvable: 8x-7y=42 8x-7(170-24x)=42 8x-1190+168x=42 176x=1232 x=1232/176=7 x=7 The solution we made for y can now be used with the solved value of x to find y's numerical value. y=170-24x y=170-24(7) y=170-168 y=2 So, finally, we get that x=7 and y=2
What is the answer to y equals 7?
If y equals 7, then y equals 7. This equation is already in final, solved state. Read it out loud and you will understand.
5x - y equals 27 5x plus 4y equals 42?
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
Y plus 7 equals 9?
Y+7=9 equals 2+7=9.
