Answer :

GIVEN:

We are given the following equation;

[tex]16x+9=9y-2x[/tex]

Required;

Solve the equation for y.

Step-by-step solution;

To solve, we simply collect like terms as follows;

[tex]\begin{gathered} Add\text{ }2x\text{ }to\text{ }both\text{ }sides: \\ 16x+2x+9=9y-2x+2x \end{gathered}[/tex]

We now have;

[tex]18x+9=9y[/tex]

Observe that -2x and +2x cancel out each other on the right hand side.

Next step, we divide both sides by 9, that is the coefficient of y.

[tex]\frac{18x+9}{9}=\frac{9y}{9}[/tex][tex]\frac{18x+9}{9}=y[/tex]

Note that we can split up the left hand side. We do this by taking both numbers in the numerator and writing each as a fraction with 9 as the denominator. This is because 9 is the LCM of both fractions as it is expressed above.

We now have;

[tex]\frac{18x}{9}+\frac{9}{9}=y[/tex]

Now we divide both fractions by any common factors;

[tex]2x+1=y[/tex]

Therefore,

ANSWER:

[tex]y=2x+1[/tex]
