2.) [tex]4y = 2y - 10 - 2[/tex]
--> [tex]4y = 2y - 8 --> 4y - 2y = -8 --> 2y = -8[/tex]
So y = -4.
3.) [tex]6x - 9x - 4 = -2x - 2[/tex]
Combine like terms:
--> [tex]-3x - 4 = -2x - 2[/tex]
Isolate x ---> [tex]-3x - (-2x) = -2 - (-4)[/tex]
----> [tex]-x = 2[/tex]
So x = -2
4.) [tex]-2(2x + 3) = -4(x + 1) - 2[/tex]
--> [tex]-4x - 6 = -4x - 4 - 2[/tex]
Combine like terms ---> [tex]-4x - 6 = -4x - 6[/tex]
This equation has many possible solutions.
5.) [tex]3(x + 2) = -5 - 2(x - 3)[/tex]
--> [tex]3x + 6 = -5 - 2x + 6[/tex]
Combine like terms ---> [tex]3x + 6 = -2x + 1[/tex]
----> [tex]3x + 2x = 1 - 6[/tex]
-----> [tex]5x = -5[/tex]
So x = -1.
6.) [tex]2(x - 3) = \frac{1}{2}(4x - 12)[/tex]
Distribute ---> [tex]2x - 6 = 2x - 6[/tex]
This equation has many possible solutions.
