Exercise 23 Page 277

Substitute (2,7) into the given equation and then simplify.

Yes

Practice makes perfect

We can determine whether (2,7) is a solution by substituting it into the equation and simplifying using the order of operations.

y=3x+1

x= 2, y= 7

7? =3( 2)+1

Multiply

7? =6+1

Add terms

7=7

Since both sides are equal, (2,7) is a solution.
