Exercise 24 Page 277

Substitute (4,22) into the given equation and then simplify.

Yes

Practice makes perfect

We can determine whether (4,22) is a solution by substituting it into the equation and simplifying using the order of operations.

y=7x-4

x= 4, y= 22

22? =7( 4)-4

Multiply

22? =28-4

Subtract term

22≠ 24

Since both sides are not equal, (4,22) is not a solution.
