Use the Distributive Property.
x=- 6.25, see solution.
To solve an equation, we should first gather all of the variable terms on one side and all of the constant terms on the other side using the Properties of Equality. In this case, we need to start by using the Distributive Property to simplify the left-hand side of the equation.
Now, we can continue to solve using the Properties of Equality.
LHS+7=RHS+7
Add terms
.LHS /- 4.=.RHS /- 4.
Put minus sign in front of fraction
Calculate quotient
The solution to the equation is x=- 6.25.
