Question

Can someone please answer this question. Solve for x.
Log(x+2)+log(x-4)=log55

Answer 1

2 log 55/26 + log 28/175
=2(log 55 − log 26) +log28 −log 175
2log(11×5)− 2log (2×13) +(4×7)−log (25×7)
=2(log11 +log5)− 2(log 2 +log 13) + log4 +log7−(log 25+log7)
=2log11 + 2log5− 2log 2 −2log 13 + log4 +log7−log 25−log7
=2log11 −2log 13 + 2log 5− 2log 2 + log2² +log7−log 5²−log7
=2log11 −2log 13 + 2log 5− 2log 2 +2log2 +log7−2log 5−log7
=2log11 −2log 13 + 2log 5 −2log 5− 2log 2 +2log2 +log7−log7
=2log11 −2log 13
=2x−2y =2(x−y)

Answer 2

do this help

Answer 3

No because x is not isolated

Answer 4

ohhh
