Answer:
A. 2x + 3y=4
Step-by-step explanation:
If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r. ... Let's look at the equation 2x - 3y = 7.
