log_{2}(x)+x=3

Solution

lo g_{2} (x) + x = 3

Solution

x = 2

Solution steps

lo g_{2} (x) + x = 3

Move

x

to the right side

lo g_{2} (x) = 3 - x

If

f (x) = g (x),

then

a^{f (x)} = a^{g (x)}

2^{l o g_{2} (x)} = 2^{3 - x}

Simplify

2^{l o g_{2} (x)} : x

x = 2^{3 - x}

Solve

x = 2^{3 - x} : x = 2

x = 2

Verify Solutions:

x = 2

True

The solution is

x = 2

Popular Examples

log_{2}(9x+2)-log_{2}(x-5)=3

lo g_{2} (9 x + 2) - lo g_{2} (x - 5) = 3

ln (x + 50) = 2

ln(x+2)-ln(4)=3

ln (x + 2) - ln (4) = 3

4 ln (x - e) = 4
