Answer:

x = $\frac{1}{5}$ , y = 6

Step-by-step explanation:

5x + y = 7 → (1)

20x + 2 = y → (2)

Substitute y = 20x + 2 into (1)

5x + 20x + 2 = 7

25x + 2 = 7 ( subtract 2 from both sides )

25x = 5 ( divide both sides by 25 )

x = $\frac{5}{25}$ = $\frac{1}{5}$

Substitute this value into (2) and evaluate

20( $\frac{1}{5}$ ) + 2 = y

4 + 2 = y , so

y = 6

Solve 6^x+2 = 10 for x using the change of base formula

pashok25 [27]

Answer:

$x\approx-0.7149$

Step-by-step explanation:

$\displaystyle 6^{x+2}=10\\\\\log_6(6^{x+2})=\log_6(10)\\\\x+2=\frac{\log(10)}{\log(6)}\\\\x+2\approx1.2851\\\\x\approx-0.7149$

Recall that the change of base formula is $\displaystyle \log_a(b)=\frac{\log(b)}{\log(a)}$
