Answer (4)

2 x + 5 = 3 1 − x / l o g 2 ​ ( ) l o g 2 ​ 2 x + 5 = l o g 2 ​ 3 1 − x x + 5 = ( 1 − x ) l o g 2 ​ 3 x + 5 = l o g 2 ​ 3 − x l o g 2 ​ 3 x + x l o g 2 ​ 3 = l o g 2 ​ 3 − 5 x ( 1 + l o g 2 ​ 3 ) = l o g 2 ​ 3 − 5 / : ( 1 + l o g 2 ​ 3 )
x = 1 + l o g 2 ​ 3 l o g 2 ​ 3 − 5 ​ − − − − − − − − − − − − − l o g 2 ​ 3 ≈ 1.5849625 − − − − − − − − − − − − − − − − x ≈ 1 + 1.5849625 1.5849625 − 5 ​ ≈ − 1.321

2^x+5 = 3^1-x take log on both sides (x+5)log2=(1-x)log3 0.3010(x+5) = (1-x)0.4771 0.3010x + 1.5050 = 0.4771 - 0.4771x 0.7781x= -1.0279 x=-1.320

To solve the equation 2 x + 5 = 3 1 − x , we take the logarithm of both sides and manipulate the equation to isolate x . The approximate solution for x rounded to three decimal places is − 1.321 .
