Question

Solve the equation 2x + 65 = 19. Explain the steps and properties you used.

Which property is the best choice to use to isolate the variable term?
OA. Multiplication Property of Equality
B. Division Property of Equality
C. Subtraction Property of Equality
D. Addition Property of Equality
Apply the property from the previous step to isolate the variable term.
(Simplify your answer. Type an equation. Use integers or fractions for any numbers in the equation.)

Answer 1

...The objective of solving an equation is to find x unknown value. we put the terms or x alone to the left of =, the numbers alone to the right of =

The terms with "x" which are already in the 1st member do not move (they are in the right place), we move the terms without x to the right.

The sign changes when it passes from one member to the other (+ becomes - and - becomes +).

we add the terms on each side of =

we divide each side of the equation by the coefficient of x

we obtain the value of x

2x+65 = 19

2x=19-65

2x=-46

x=-46/2 =-23
