solve for x 89x7x8Solution 8x 7 72 Add 7 to both sides to

solve for x 8^(9x)=7^(x+8)

8/x - 7 = 7/2. Add 7 to both sides to get 8/x = 7+7/2 = 21/2 Take the inverse of both sides to get x/8 = 2/21 Multiply both sides by 8 to get x = 16/21 If you meant 8/(x-7) = 7/2, solution is similar. Multiply both sides by x-7 to get 8 = (x-7)*7/2 Multiply both sides by 2/7 to get 16/7 = x-7 Add 7 to both sides to get x = 7 + 16/7 = 65/7 = x
