5 + 2x = 2x + 6<br><br>Step by step please​
Fiesta28 [93]

Answer:

5 + 2x=2x + 6

Subtract 5 from both sides.

2x =2x + 6 - 5

Combine like terms (numbers).

2x = 2x + 1

Subtract 2x from both sides.

0 = 1

Since 0 doesn’t equal 1, there is no real solution to the problem.

Anyone help me. ....​
weeeeeb [17]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

All the exponents inside the parenthesis are multiplied by the exponent outside the parenthesis.

Then

\frac{m^{-7}n^{14}  }{m^{-25}n^{40}  } ÷ \frac{m^{-21}n^{42}  }{m^{-25}n^{40}  }

[ Using the rule \frac{a^{m} }{a^{n} } = a^{(m-n)} ]

= m^{(-7-14)} n^{(14-(-28)} ÷ m^{(-15-10)} n^{(25-(-15)}

= m^{-21} n^{14+28} ÷ m^{-25} n^{25+15}

= \frac{m^{-21}n^{42}  }{m^{-25}n^{40}  }

= m^{(-21-(-25))} n^{(42-40)}

= m^{(-21+25)} n²

= m^{4} n² = m^{x} n^{y} , so x = 4 and y = 2

Then

m^{x-2y} = m^{4-2(2)} = m^{4-4} = m^{0} = 1 ← as required
