If y varies directly with x and y equals 6 and x equals -3 find y when x equals 4?
y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2 y/4=-2 y=-8
How do you solve y equals mx plus b solve for b?
b = y - mx.
Y-b divided m equals x solve for y?
y = mx + b
Y equals 6x-16 y equals -2x plus 8?
y=6x-16 y=-2x+8
What is the answer to 20 equals 8 more than a number y?
20 equals 8 more than a number y 20=y+8
How do you solve y equals 3 8?
y = 3 x (times) 8.
How do you solve the slope y equals 2x plus 8?
8
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
How do you solve 16x plus 4y equals 8?
You can't solve it. But you can simplify it to get: 4x+y=2
If 2 plus 2 equals x and x2 equals y and y-x equals a and a plus y equals b what is b?
in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
How do you solve y over 4 equals 10 over 8?
y/4 = 10/8 Multiply both sides by 4:- y = 40/8 y = 5
How do you solve equation 8 equals y minus -1?

How would you solve for y in this problem 4x plus y equals 8?
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
Solve using elimination x plus y equals 8 and x minus y equals 6?
X + y = 8 x - y = 6 add equations to eliminate y 2x = 14 x = 7 substitute 7 + y = 8 y = 1
How do you solve the system of equation 5x plus y equals -7 amd 3x plus y equals 15?
