himpunan penyelesaian dari 2log(2×+7)=2 pleaseee tolong ya

Logaritma
²log (2x + 7) = 2
2x + 7 = 2²
2x + 7 = 4
2x = 4 - 7
2x = - 3
x = -3/2

²log(2×+7)=2
☞ ²log(2x+7) = 2 , x > - 7/2
✐ 2x + 7 = 2²
✐ 2x + 7 = 4
✐ 2x = 4-7
✐ 2x = -3
✐ x = - 3/2 , x > - 7/2
✐ x = - 3/2
ATAU
✐ x = -1 1/2 (pecahan campuran)
ATAU
✐ x = -1,5
