Question

Identify the value for the variable. What is the value of x in this simplified expression? 7-9 · 7-3 = 7x

Answer 1

Using PEMDAS:
7 - 9 x 7 - 3 = 7x
7 - 63 - 3 = 7x
-59 = 7x
/7 /7
-8.43 = x

Answer 2

Solve for x:
-59 = 7 x

-59 = 7 x is equivalent to 7 x = -59:
7 x = -59

Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7
