How do you solve y - 3 equals?
y - 3 = 0 y = 3
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)
Square root 2y plus 3 equals 11 solve equation for y?
√(2y) + 3 = 11 √(2y) = 11 - 3 = 8 √2 x √y = 8 √y = 8/√2 y = (8/√2)2 = 64/2 = 32
Which method would be best to solve x plus y equals 13 and -x plus y equals 3?

How do you solve y - 3 equals?
y - 3 = 0 y = 3
How do you solve 3y plus 8 equals 3?
3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)
How do you solve the slope y equals 2x plus 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)
Square root 2y plus 3 equals 11 solve equation for y?
√(2y) + 3 = 11 √(2y) = 11 - 3 = 8 √2 x √y = 8 √y = 8/√2 y = (8/√2)2 = 64/2 = 32
Which method would be best to solve x plus y equals 13 and -x plus y equals 3?

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
Solve this system x - y equals 8 2x plus y equals 7?
Add the two equations: 3x = 15 Divide by 3: x = 5, making y = -3. Job done.
What is the equation y equals 5x-3 telling you?

How do you solve x equals 4 y equals x plus 3?
x=4 y=x+3 y=4+3 y=7
Solve for y 4x-y equals 7?
-3
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
