Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.
<h3>What is the leading coefficient of a polynomial?</h3>
The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.
In this problem, the expression is given by:
7m² + 19.
The highest exponent is of 2, in m², hence the leading coefficient is of 7.

Answer:
/ Solve equation [2] for the variable y
[2] 7y = 12x + 17
[2] y = 12x/7 + 17/7
// Plug this in for variable y in equation [1]
[1] 9x - 2•(12x/7+17/7) = -3
[1] 39x/7 = 13/7
[1] 39x = 13
// Solve equation [1] for the variable x
[1] 39x = 13
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 12x/7+17/7
// Use the x value to solve for y
y = (12/7)(1/3)+17/7 = 3
Solution :
{x,y} = {1/3,3}
