Answer:

-6=n

Step-by-step explanation:

2×n= 2n

2×5=10

2n+10= -2

Subtract 10 from both sides, leaving you with 2n= -12

-12/2= -6

Solve this equation please

nalin [4]

Step-by-step explanation:

Number 1

$log_{10}( {x}^{2} - 3x + 12 ) = 1 \\ log_{10}( {x}^{2} - 3x + 12 ) = log_{10}(10) \\ cancelling \: both \: logs \: we \: have \\ {x}^{2} - 3x + 12 = 10 \\ {x}^{2} - 3x + 12 - 10 = 0 \\ {x}^{2} - 3x + 2 = 0 \\$

$solve \: \: by \: factorisation \: method \\ {x}^{2} - 2x - x + 2 \\ {x}(x - 2) \: - 1(x - 2) \\ (x - 2)(x - 1) \\ therefore \: x = 2 \: or \: x = 1$
