Question

Persamaan matematika jika x=8 dan x=30
1.x+9=
2.12+x=
3.x-3=
4.x-6=
5.40-x=

Answer 1

Jika x = 8
1.) X+9 = 8+9 = 17
2.) 12+x = 12+8 = 20
3.) x-3 = 8-3 = 5
4.) x-6 = 8-6 = 2
5.) 40-x = 40-8 = 32

jika x = 30
1.) x+9 = 30+9 = 39
2.) 12+x = 12+30 = 42
3.) x-3 = 30-3 = 27
4.) x-6 = 30-6 = 24
5.) 40-x = 40-30 = 10

tinggal disubtitusikan aja , dimasukkan x nya
