Answer:
Equation have Unique solution i.e [tex]x=-20[/tex]
Step-by-step explanation:
Given Equation:
[tex]-6(x+7)=-4x-2[/tex]
Solving the Equation for 'x'.
[tex]-6(x)-6(7)=-4x-2\\\\-6x-42=-4x-2[/tex]
Adding '[tex]4x[/tex]' both sides:
[tex]-6x+4x-42=-4x+4x-2\\\\-6x+4x-42=-2\\\\-2x-42=-2[/tex]
Adding '42' both sides:
[tex]-2x-42+42=-2+42\\\\-2x=40[/tex]
[tex]x=\frac{40}{-2} \\\\x=-20[/tex]
The equation have Unique solution with the value of [tex]x=-20[/tex]
