Question

is j = 9 a solution to this equation? 13 = 2j yes no

Explanation:

Step1: Substitute j=9 into the equation

Substitute \( j = 9 \) into the right - hand side of the equation \( 13=2j \). The right - hand side becomes \( 2\times9 \).

Step2: Calculate the value of 2×9

According to the multiplication operation, \( 2\times9 = 18 \).

Step3: Compare with the left - hand side

The left - hand side of the equation is 13, and the value we got from substituting \( j = 9 \) is 18. Since \( 13
eq18 \), \( j = 9 \) is not a solution to the equation \( 13 = 2j \).

Answer:

no
