answers:
1) [tex]2x + 4 = 12[/tex] | subtract the 4 and move it over to 12
[tex]2x = 4[/tex] | divide by 2
[tex]x = 4[/tex] | final answer
2) [tex]3x - 3 = 6[/tex] | add the 3 and move it over to 6
[tex]3x = 9[/tex] | divide by 3
[tex]x = 3[/tex] | final answer
3) [tex]3 - 2x = 7[/tex] | subtract the 3 and move it over to the 7
[tex]-2x = 4[/tex] | divide by -2
[tex]x = 3[/tex] | final answer
4) [tex]\frac{2}{3} x = 6[/tex] | divide by 2/3
[tex]x=9[/tex] | final answer
6) [tex]2x+ 3 + x = -2[/tex] | combine like terms
[tex]3x + 3 = -2[/tex] | subtract 3 and move it over to -2
[tex]3x = -5[/tex] | divide by 3
[tex]x= -1.6666666667[/tex] | final answer
6) [tex]4x = x - 9[/tex] | subtract x and move it over to 4x
[tex]3x = 9[/tex] | divide by 3
[tex]x = 3[/tex] | final answer
hope it helps!❤ from peachimin
