How can we isolate y on the left-hand side?
y=-4
To solve the equation we have to isolate y on one side of the equation. By dividing both sides of the equation by -7, we can remove the coefficient from y.
.LHS /(-7).=.RHS /(-7).
- a/- b=a/b
Calculate quotient
To check that we have the correct solution, we can substitute y=-4 into the original equation.
Since both sides are equal, we can conclude that y=-4 is the correct solution.
