Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
x + (3x - 4) = 5 - (-7 - 3x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute negative: x + 3x - 4 = 5 + 7 + 3x
- [Addition] Combine like terms: 4x - 4 = 12 + 3x
- [Subtraction Property of Equality] Subtract 3x on both sides: x - 4 = 12
- [Addition Property of Equality] Add 4 on both sides: x = 16
(7^x)^4 is equal to 7^(4x).
7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5.
7^5 / 7^(3x) is equal to 7^(5 - 3x).
you wind up with 7^(4x) is equal to 7^(5 - 3x)
this is true if and only if 4x = 5 - 3x.
