Answer:

\frac{12a-14b}{21}

Step-by-step explanation:

Express the 2 fractions with a common denominator of 21

multiply numerator/denominator of first fraction by 3

multiply numerator/denominator of second fraction by 7

\frac{4a(3)}{7(3)} - \frac{2b(7)}{3(7)}

= \frac{12a}{21} - \frac{14b}{21}

= \frac{12a-14b}{21}

<h3>How to Graph a Linear Equation?</h3>

The slope (m) and the y-intercept (b) of a linear equation can easily be determined by writing a linear equation in slope-intercept form, y = mx + b.

The slope of the line is the rise/run, while the y-intercept tells us at what point on the y-axis the line intercepts.

Rewrite 3x + 5y = 12, in slope-intercept form:

5y = - 3x + 12

y = -3/5x + 12/5

The slope of the line of the equation is -3/5 while the y-intercept is 12/5.

Therefore, the graph of the equation, 3x + 5y = 12, is the graph attached in the image below.
