We are given the following equation:
[tex]3x+7=-5[/tex]To solve for "x", first we will subtract 7 to both sides:
[tex]3x+7-7=-5-7[/tex]Solving the operations:
[tex]3x=-12[/tex]Now we will divide both sides by 3:
[tex]\frac{3x}{3}=-\frac{12}{3}[/tex]Solving the operations:
[tex]x=-4[/tex]Therefore, the value of "x" is -4
