2x + xy = xz + 3 Solve for x
1/x + 1/2 = y Solve for x
I realize i could put this in the calculator but I need to show my work. By the way those are 2 sepreatae questions
2x + xy = xz + 3 Solve for x
Solve for x:
2 x+x y = 3+x z
Collect in terms of x:
x (y+2) = 3+x z
Subtract x z from both sides:
x (2+y-z) = 3
Divide both sides by 2+y-z:
Answer: |x = 3/(2+y-z)
1/x + 1/2 = y Solve for x
Solve for x:
1/2+1/x = y
Bring 1/2+1/x together using the common denominator 2 x:
(x+2)/(2 x) = y
Multiply both sides by 2 x:
x+2 = 2 x y
Subtract 2+2 x y from both sides:
x (1-2 y) = -2
Divide both sides by 1-2 y:
Answer: |x = -2/(1-2 y)
