Whats the solution to the given system of equations? <br><br> -5x+8y=-36 <br> 5x+7y=6

AleksandrR [38]

Answer:

x=4, y=-2

Step-by-step explanation:

-5x+8y=-36

5x+7y=6

eqn 1+ eqn 2 gives

15y=-30

divide both sides by 15

y=-2, put in eqn 2

5x+7(-2)=6

5x=20 divide both sides by 5

x=4

Ln 5 - ln a + 6 ln b- 6 ln c, please condense this logarithm, I fear I messed it up

NemiM [27]

$Use:\\lnx-lny=ln(\frac{x}{y})\\\\lnx+lny=ln(x\cdot y)\\\\lnx^y=y\cdot lnx$

$ln5-lna+6lnb-6lnc=ln\frac{5}{a}+lnb^6-lnc^6=ln\frac{5}{a}+ln\frac{b^6}{c^6}\\\\=\boxed{ln\frac{5b^6}{ac^6}}\\\\\\where:a > 0;\ b > 0\ and\ c > 0$
