| 4x-6=x+9
-x���� -x 3x-6=� +9 �� +6=� +6 3x�� =�� 15 /3��������� /3 �x��� =��� 5 |
1)Subtract the x from both sides�
2)Add six to both sides� 3)Divide both sides by three 4)The answer yields to five.� |

| �� 2(-3a+5)=-4(a+4) | 1) Distribute the 2 into the (-3a+5) and the -4 into the (a+4) |
| �������� -6a+10=-4a+16
��������� -10������� -10 |
2) subtract the 10 from both sides of the equation.� |
| ���������������������
-6a= -4a+6
�������� +4a��� +4a |
3) Add 4a to both sides of the equation� |
| �������������
-2a= 6
��������� /-2� /-2 |
4) divide by -2a on both sides of the equation� |
| ������������������� a=-3 | 5) The answer is A=-3 |
