determine whether 9 is the solution of the equation 7(x-2)=50
7(x-2)=50
7x - 14 = 50
7x = 64
x = 64/7
x = ?
7(9-2)=50
7(7)=50?? True or false?
To determine whether 9 is the solution of the equation 7(x-2) = 50, we need to substitute 9 into the equation in place of the variable x and see if both sides of the equation are equal.
Step 1: Replace x with 9 in the equation:
7(9 - 2) = 50
Step 2: Simplify the equation:
7(7) = 50
49 = 50
Step 3: Compare both sides of the equation to check if they are equal. In this case, 49 is not equal to 50.
Since the equation is not balanced (49 is not equal to 50), it means that 9 is not the solution to the equation 7(x-2) = 50.
