Exercise 1 Page 266

Substitute (2,21) into the given equation and then simplify.

No

Practice makes perfect
We can determine whether (2,21) is a solution by substituting it into the equation and simplifying using the order of operations.
y=7x
SubstituteII

x= 2, y= 21

21? =7( 2)
Multiply

Multiply

21≠ 14
Since both sides are not equal, (2,21) is not a solution.
