2/3x+2=1/4x-3, nilai dari 2x+19 adalah...

2/3x + 2 = 1/4x - 3
2/3x - 1/4x = -3 - 2
8/12x - 3/12x = -5
5/12x = -5
x = -5 X 12/5
x = -60/5
x = -12

2x + 19
= 2(-12) + 19
= -24 + 19
= -5

2/3x+2 = 1/4x - 3
2/3x - 1/4x = -3 - 2
8/12x - 3/12x = -5
5/12x = -5
5/-5 = 12x
-1/12 = x

jika x = -1/12, maka 2x+19 adalah 
2(-1/12) + 19
= -2/12 + 19
= -1/6 + 19
= 95/114
