1. Jawaban BenCraft
x+3 = 2
x = 2 - 3
x = 1
x - 5 = 3
x = 3 + 5
x = 8
-x + 2 = 2
-x = 2 - 2
-x = 0
x = 0
2x + 2 = 3
2x = 3-2
2x = 1
x = 1/2
2x - 4 = 1
2x = 1+4
2x = 5
x =5/2 -
2. Jawaban iirfan853
a.x+3=2
x=2-3
x=-1
b.x-5=3
x=3+5
x=8
c.-x+2=2
-x=2-2
x=0
d.2x+2=3
2x=3-2
2x= 1
x = ½
e. 2x -4= 1
2x = 1+4
2x = 5
x = 5/2
