Tell wheather the given value of the varible is a solution of the equation.
4x+13=-9-3(x+9);x=-7.
Let x=-7 and see if both sides are equal when x=-7. If it does, it is a solution. If it's not, it's not.
:
4(-7)+13=-9-3(-7+9)
-28+13=-9-3(2)
-15=-9-6
-15=-15
Yes, x=-7 is a solution.
Happy Calculating!!!
