What is the solution to the equation x over 3 + x over 6 = 7 over 2

Romashka [77]

Answer:

x=7

Step-by-step explanation:

The given equation is:

$\frac{x}{3}+\frac{x}{6} = \frac{7}{2}$

Multiplying both sides by LCM of 3 and 6

So,

$\frac{x}{3}*6+\frac{x}{6}*6 = \frac{7}{2}*6\\2x+x=7*3\\3x=21\\\frac{3x}{3} =\frac{2}{3}\\ x=7$

Hence, the solution of the equation is x=7 ..

Solve for the value of X in 9^x+4(3^x+1)+27=0

worty [1.4K]

Answer:

No solutions

Step-by-step explanation:

$9^x + 4(3^x + 1) + 27 = 0\\3^{2x} + 4 \cdot 3^x + 31 = 0$

Substitute 3^x with t and we get.

$t^2 + 4t + 31 = 0\\\triangle = 16 - 4 \cdot 31 = -108 < 0 => t_{12} \notin R => x \notin R$
