To isolate x, we need to get rid of the positive three on the left side.We subtract three from both sides to maintain the equation's balance.The positive and negative threes cancel out on each side.After simplifying, we have two x equals negative ten.The equation remains balanced, with two x on the left equal to negative ten on the right.Now that we have 2x equals negative 10, we need to divide both sides by 2 to solve for x.When we divide both sides by 2, we write it as a fraction.Dividing negative 10 by 2 means splitting it into two equal groups.This gives us x equals negative 5.Let's verify our solution by plugging negative 5 back into the original equation.Starting with our original equation, two x plus three equals negative seven.We substitute negative 5 for x.Two times negative 5 equals negative 10.Negative 10 plus 3 equals negative 7, confirming our solution is correct.
