9^{x + 2} = 2 7^{x}

Solution

x = 4

Solution steps

9^{x + 2} = 2 7^{x}

Apply exponent rules

2 (x + 2) = 3 x

Solve

2 (x + 2) = 3 x : x = 4

x = 4

Popular Examples

solvefor x,(19)*y=(c_{1}+c_{2}*x)*e^x solve for

x, (19) \cdot y = (c_{1} + c_{2} \cdot x) \cdot e^{x}

(sqrt(5+\sqrt{24)})^x+(sqrt(5-\sqrt{24)})^x=10

(5 + 24)^{x} + (5 - 24)^{x} = 10

7^{1-x}=49^{3x+1}

7^{1 - x} = 4 9^{3 x + 1}

solvefor x,e^y=2^x solve for

x, e^{y} = 2^{x}

2^{2x}-2^{x+1}=8

2^{2 x} - 2^{x + 1} = 8
