1. Persamaan linear satu variabel a). 8+2× = 40 b). 12-3× = -3 c). 2(×-5) = 6 tolong di bantu pr buat hari senin

a. 8+2x=40
2x=40-8
2x=32
x=32/2
x=16

b. 12-3x=-3
-3x=-3-12
-3x=-15
x=-15/-3
x=5

c. 2(x-5)=6
2x-10=6
2x=6+10
2x=16
x=16/2
x=8

a) 8+ 2x = 40
2x=40-8
2x=32
x=16

b) 12-3x=-3
-3x=-3-12
-3x=-15
x=-15÷-3
x=-5

c) 2(x-5)=6
2x-10=6
2x=6+10
2x=16
x=16÷2
x=8
