Answer: 12.5

You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."

subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"

5/7^3 = 5(7^x) Thank you for helping!!

SIZIF [17.4K]

When solving this equation you get x = -3.

To solve this, simply follow the order of operations for solving.

$\frac{5}{7^{3}} = 5(7^{x} )$ ----> start by dividing both sides by 5

$\frac{1}{7^{3}} = (7^{x} )$ -----> Now you can transform the front side of the equation to use negative exponents.

$7^{-3} = 7^{x}$

Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.

-3 = x
