Question

this equation and graph represent the situation: comic books cost $2 each and magazines cost $4 each. how many comic books and magazines can you buy with exactly $30? is (1, 7) a solution to the equation? 2c + 4m = 30 no, (1, 7) is not a solution. yes, (1, 7) is a solution.

Explanation:

Step1: Substitute values into equation

Substitute $c=1$, $m=7$ into $2c + 4m = 30$:
$2(1) + 4(7)$

Step2: Calculate left-hand side

$2 + 28 = 30$

Step3: Compare to right-hand side

Left-hand side ($30$) equals right-hand side ($30$)

Answer:

Yes, (1, 7) is a solution.
