Answer:
D) x= 2 , B) x= - 6
Explanation:
D) 2 + 3x = 6x - 4
Arrange x with x and constant with constant, (the signs +ve and - ve changes while arranging them to other side)
2 + 4 = - 3x + 6x
6 = 3x
(Here the 3 was multiplying with x and when you bring it to the other side it divides by 6)
6/3 = x
2 = x
B) 18 + 4x = - 6
Arrange them again,
4x = - 18 - 6
4x = - 24
x = - 24/4
x = - 6
