May 19, 2017 · First, multiply each side of the equation by 6 to eliminate the fractions while keeping the equation balanced. 6 is the lowest common denominator of the two fractions: 6(3w +7 6 + 2w +2 3) = …

First, multiply each side of the equation by #color (red) (12)# to eliminate the fractions while keeping the equation balanced. We multiply by #color (red) (12)# because it is the LCD (Lowest Common …

Mar 5, 2017 · Next, combine like terms on the left side of the equation: (− 7 + 3)y +9 = 17 −4y + 9 = 17 Then, subtract 9 from each side of the equation to isolate the y term while keeping the equation …

Explanation: Multiply each side of the equation by #color (red) (5)# to solve for #x# while keeping the equation balanced:

"C"_3"H"_8 Start by writing a balanced chemical equation that describes the combustion of a hydrocarbon "C"_x"H"_y "C"_ x"H"_ (y(g)) + (x + y/4)"O"_ (2(g)) -> x"CO"_ (2(g)) + y/2"H"_ …

DeltaH_"rxn" = -"399.3 kJ" I assume that you mistyped the chemical equation for that reaction, since it's pretty clear that x has to be equal to 2. So, the balanced chemical equation for your reaction is …

Now, subtract #color (red) (2)# from each side of the equation and put the equation in standard form while keeping the equation balanced:

Dec 1, 2016 · x = 6 First, expand the terms in parenthesis and combine like terms on the right side of the equation. Remember to mind the signs when expanding the parenthesis: 4x - x + 1 = 2x + 7 (4 - 1)x …

Cube each side of the equation to solve for x while keeping the equation balanced: (3√x)3 = −23 x = − 8
