X plus 5y equals 0?
x + 5y = 0 so x = -5y or y = -x/5 You can express x in terms of y or y in terms of x but it is not possible to solve a single linear equation in two variables.
Express x in terms of y and z when 1overx equals 1overy plus 1overz?
1/x = 1/y + 1/zx = ( yz ) / (y + z)
If log y equals 0.7 plus 2 times log x express y in terms of x?
It cannot be done because the base for the second log is not given.
If x equals y-3 and y equals z2 what is x terms of z?
x= z2 - 3
3 terms multiply by 3 terms?

How do you solve the problem 3X plus 5Y equals 7?
To solve for two unknowns (x and y) you need two independent equations. All that you can do with the above is to express x in terms of y, as follows: 3X + 5Y = 7 => 3X = 7 - 5Y or X = (7 - 5Y)/3 or you can express y in terms of x: Y = (7 - 3X)/5
If x equals y-3 and y equals z2 what is x terms of z?
x= z2 - 3

5X plus 5y equals -7 how do you solve by elimination?
To solve for two unknowns (x and y) you need two independent equations. All that you can do with the above is to express x in terms of y, as follows: 5x + 5y = -7 x + y = -7/5 x = -7/5 -y Similarly, you could express y in terms of x as: y = -7/5 -x IF, you had a value for either x or y from some other equation (or other source), you could substitute that value in either of these equations to solve for the other.
If y times x-1 equals z then x equals?
y * (x-1) = z Express as x,divide both sides by y(x - 1) = z/yadd 1 on both sidesx = z/y + 1
What is x in terms of y when xy equals 6x plus 6y?
x = 6y over (y-6)
Can the equation x equals y-siny be rearranged in terms of y?
Yes: it is already in terms of y so nothing needs to be done.
What is y equals x plus 2 y equals 2-x?
y = x + 2 y = 2 - x so x + 2 = 2 - x Combining like terms: 2x = 0 so that x = 0 and then, from the first equation, y = 2
If tan y equals to x where y is acute find 2 sin y in terms of x?
2sin(y) = 2x/sqrt(1+x^2)
