Step-by-step explanation:
a)3 +X =0(Take the 3 to the left side)
Therefore: X=-3
b)23x + 2 =2 (Take the 2 to the left side)
Therefore:23x =0
(divide 23 with 23 and divide 0 by 23)
Therefore: X= 0
c) 12- 7+ 4X = 25(Take 12 and -7 to the left side)
Therefore: 4x= 25- 12+7
Therefore: 4x= 20(Then divide 4 by 4 and then divide 20 by 4)
Therefore: X=5
d)5x -3x =30
Therefore:2x =30(divide 30 by 2)
Therefore:X=15
e)4x +10= 45-3x(Move the like terms)
Therefore:4x+3x =45-10
Therefore:7x =35(Divide 7 by 7 and then divide 7 by 35)
Therefore:X= 5.
