Somebody please help me.. The math
1 answer:
#1.
2(x-3) = 4(x-2)
distribute.
2x-6 = 4x-8
subtract 2x from each side
-6 = 2x-8
add 8 to each side
2 = 2x
divide each side by 2
1 = x
-------------------
2/6 = 1/3
for any exponents, subtract the one on top by the one on the bottom.
x^0 / x^-2 = x^(0-(-2)) = x^2
y^-2 / y^-2 = y^(-2-(-2) = y^0 = 1, so don't write this
z^1 / z ^ 3 = z^(1-3) = z^-2 or z^2 on the bottom
2(x-3) = 4(x-2)
