Solve for x. 9^x+15=3^7x
Art [367]

The solution is x = 6

Step-by-step explanation:

Let us revise some rules of the exponents

  • If a^{n}=a^{m} , then n = m
  • (a^{n})^{m}=a^{nm}

∵ 9^{(x+15)}=3^{7x}

∵ 9 = 3 × 3

∴ 9 = 3²

- Substitute 9 by 3² in the equation above

∴ (3^{2})^{(x+15)}=3^{7x}

- Use the second rule above for the left hand side

∵ (3^{2})^{(x+15)}=3^{2(x+15)}

∴ (3^{2})^{(x+15)}=3^{2x+30}

∴ 3^{2x+30}=3^{7x}

- By using the first rule above

∴ 2x + 30 = 7x

- Subtract 2x from both sides

∴ 30 = 5x

- Divide both sides by 5

∴ 6 = x

The solution is x = 6

% change = (new value - old value) old value x 100 = (1,045 - 950)/950 x 100 = 95/950 x 100 = 0.1 x 100 = 10%
