What is the answer to 9 plus 3y-2y equals 14?
y=14 here is how you go about solving the problem 3y-2y=14 first set up equation y=14 combine like terms and get 1y but we do not need 1 in front because the variable has invisible 1
How do you solve negative one half plus 3y equals 4y?
When solving an algebraic equation such as this one, just remember to do what you need to in order to get the variable (y) by itself. And always do the same thing to both sides of the equation. So we start with: -1/2 + 3y = 4y Next combine the y's by subtracting 3y from both sides, which gives us: -1/2 + 3y - 3y = 4y - 3y -1/2 = y so the answer is y= -1/2
X plus y equals 15 and 4x plus 3y equals 38?
rewrite first equation: x = 15 - y substitute into second equation for x: 4(15 - y) + 3y = 38 distribute and simplify: 60 - y = 38 solve: y = 22 plug back into first equation: x = -7 -OR- multiply first equation by -3: -3x - 3y = -45 add new equation to second equation: 1x + 0y = -7 or x = -7 plug back into first equation: y = 22
What is the problem for 4y plus 7-y equals 10 plus 3y?
4y + 7 - y = 10 + 3y My next step is to combine the y's on the left, 3y + 7 = 10 + 3y If I then subtract 3y from both sides I obtain 7 = 10 which is not a true statement. Hence, the equation that you presented is invalid.
If r 5z then 15z 3y then r?
If r = 5z, then 15z = 3y, then r = y. This can be solved easily by solving for z in the second equation and substituting into the first equation.
What is the equation for 3y plus 3y equals -1?
The equation for 3y + 3y = -1 is 3y + 3y = -1.
-x plus 3y equals -2?

Solving by subsitution x - 2y equals 0 4x - 3y equals 15?
x - 2y = 04x - 3y = 15From the first equation, x = 2y.SUBSTITUTING this value of x in the second equation,4*(2y) - 3y = 15 ie 8y - 3y = 15 or 5y = 15 so that y = 3and then, x = 2y gives x = 2*3 = 6Answer: x = 6, y = 3
2x plus 3y equal 40 -2x plus 2y equal 20?
2x+3y=40-2x+2y=20Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.3y=-2xDivide each term in the equation by 3.(3y)/(3)=-(2x)/(3)Simplify the left-hand side of the equation by canceling the common terms.y=-(2x)/(3)if you were solving for x It would be x=-(3y)/2

What is the equation x equals 3y in standard form?
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
-2X plus 3Y equals 8?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
X plus y equals 15 and 4x plus 3y equals 38?
rewrite first equation: x = 15 - y substitute into second equation for x: 4(15 - y) + 3y = 38 distribute and simplify: 60 - y = 38 solve: y = 22 plug back into first equation: x = -7 -OR- multiply first equation by -3: -3x - 3y = -45 add new equation to second equation: 1x + 0y = -7 or x = -7 plug back into first equation: y = 22
y+1/y^2-6y+8 - 3/y^2-16?
Removing the brackets: 4y-4-y-2 = 3y-6 simplified
What is the problem for 4y plus 7-y equals 10 plus 3y?
4y + 7 - y = 10 + 3y My next step is to combine the y's on the left, 3y + 7 = 10 + 3y If I then subtract 3y from both sides I obtain 7 = 10 which is not a true statement. Hence, the equation that you presented is invalid.
