Answer:
[tex]3x = -9[/tex]
Step-by-step explanation:
Move all terms containing x to the left side of the equation.
[tex]2x-4=-10[/tex]
Move all terms not containing x to the right side of the equation.
[tex]2x=-6[/tex]
Divide each term by [tex]2[/tex] and simplify.
[tex]x=-3[/tex]
Replace the variable [tex]x[/tex] with [tex]-3[/tex] in the expression.
[tex]3(-3)[/tex]
Multiply [tex]3[/tex] by [tex]-3[/tex]
[tex]-9[/tex]
