How can you isolate x on the left-hand side?
x=-4
To solve the equation we need to isolate x on one side of the equation. By subtracting 7 from both sides, we can cancel it from the left-hand side.
Therefore, x=-4 is the solution to the equation. To check that we have the correct solution, we can substitute x=-4 into the original equation and simplify.
x= -4
Commutative Property of Addition
a+(- b)=a-b
Subtract term
Since the left-hand side and right-hand side are equal, x=-4 is a correct solution.
