Question 8 • Mathematics 8

Which steps can be used in order to determine the solution to negative 1 point 3 plus 4 point 6 x is equal to 0 point 3 plus 4 x ?

Answer

Add 1 point 3 to both sides of the equation, subtract 4 point 6 x from both sides of the equation, then divide both sides by the coefficient of x .

Subtract 1 point 3 from both sides of the equation, subtract 4 point 6 x from both sides of the equation, then divide both sides by the coefficient of x .

Add 1 point 3 to both sides of the equation, subtract 4 x from both sides of the equation, then divide both sides by the coefficient of x .

Subtract 1 point 3 from both sides of the equation, add 4 x to both sides of the equation, then divide by the coefficient of x .

Explanation

Add 1.3 to both sides to remove −1.3, then subtract 4x from both sides to collect the x-terms on the left. This gives 0.6x = 1.6, so divide both sides by the coefficient 0.6 to find x. These steps match choice A, “Add 1.3 to both sides” and then subtract 4.6x? Wait, the equation requires subtracting 4x, not 4.6x.
