The value of n and m are 110 and 20 respectively if the equations are 2n + 3m = 280 and 2n + 5m = 320.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two linear equations are:
2n + 3m = 280
2n + 5m = 320
Using the elimination method:
Because the coefficient for n is the same in both equations
-2m = - 40
m = 20
n = 110
Thus, the value of n and m are 110 and 20 respectively if the equations are 2n + 3m = 280 and 2n + 5m = 320.
