Where is y in this equation? 2x-3=9. First, you add 2 to both sides, and you get 2x=12. Divide both sides by 2;
so, x=6.

How do you solve y-4 equals 9?
y - 4 = 9 y - 4 + 4 = 9 + 4 y = 13
What is the value of 2x3 plus 15y if x equals -7 and y equals 2?
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
Solve using substitution x plus y equals 3 and y equals 9?
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
How do you solve 3 divided by y plus 7 divided by y equals 9?
3/Y+7\Y=9 =>Y=10\9
How do you solve 9x plus y equals 22?
9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
How do you solve y-4 equals 9?
y - 4 = 9 y - 4 + 4 = 9 + 4 y = 13
What is the value of 2x3 plus 15y if x equals -7 and y equals 2?
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
Solve using substitution x plus y equals 3 and y equals 9?
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
How do you solve 3 divided by y plus 7 divided by y equals 9?
3/Y+7\Y=9 =>Y=10\9
What is the x and y intercept of x-3 y equals 9?
Set x=0, solve for y, which is the y intercept: 0 - 3y = 9 --> y = -3. Set y=0 and solve for x = 9 for x-intercept.
How do you solve 9x plus y equals 22?
9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x
How do you solve for y 3x-y equals 12?
-9
How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
Solve the following system of equations 5x plus y equals -9 -5x plus 2y equals 0?
x = -1.2, 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)
How do you solve -y plus y?
-y + y equals 0.
