9^{x + 2} = 2 7^{x - 1}

Solution

x = 7

Solution steps

9^{x + 2} = 2 7^{x - 1}

Apply exponent rules

2 (x + 2) = 3 (x - 1) : x = 7

x = 7

Popular Examples

2^{3x+9}=4^{x+3}

2^{3 x + 9} = 4^{x + 3}

9^{x+2}=27^{x-3}

9^{x + 2} = 2 7^{x - 3}

2^{(x-3)/(2x-1)}=sqrt(8)

2^{\frac{x - 3}{2 x - 1}} = 8
