Question

kenneth wants to solve the system of equations shown below. he made two tables showing the value of y for different values of x. kenneth looks at the graph and says the solution is (1.5, 3). substitute 1.5 for x and 3 for y in the first equation. y = 2x \square = 2(?)

Explanation:

Step1: Substitute y=3 into left side

$3 = 2(\text{?})$

Step2: Substitute x=1.5 into right side

$3 = 2(1.5)$

Step3: Verify equality

$3 = 3$

Answer:

Left box: $3$, Right box (the "?"): $1.5$
