|
x + y = 10
plot the graph to get the answer
Let’s say the two numbers are x and y, where x is the larger number and y is the smaller number. From the first statement, we know that the sum of the two numbers is 24, so we can write the equation: x + y = 24.
plot the graph by substituting different values of x to get different values of y
Draw the graphs by making equations of given information
solve this system using substitution or elimination method
plot the graph of the given equations
Let’s say the two numbers are x and y, where x is the larger number and y is the smaller number. From the first statement, we know that the sum of the two numbers is 25, so we can write the equation: x + y = 25.
Let’s say the two consecutive even integers are x and x + 2, where x is the smaller integer. From the statement, we know that the sum of the reciprocals of the two consecutive even integers is 4/15
