Question

Tolong bantuannya buat soal nomor 23 dan 24 yaa

Answer 1

38 + 38 + 23 + 23 + 12 + 12 = 146

y = 180 - (4x + 22)
 = 180 - 4x - 22
 = 158 - 4x

3x + 2 + 2x + 158 - 4x = 180
x = 20

y = 158 - 80 = 78

Answer 2

Numb 23
(2x23)+(2x38)+(2x12)=46+76+24=146

numb 24
2x+3x+2=4x+22
5x+2=4x+22
x=20
4.20+22=80+22=108
y=180-108=72
