Answer:
=63jx
Step-by-step explanation:
1) 2+5=7
2) 9 x 7jx=63jx
Answer:
Example 2 Evaluate 5x2 − 2( y + 1) + 9 when x = 2 and y = 1. 5x2 − 2( y + 1) + 9 = 5(2)2 ... In this lesson, you will. ○ use addition or subtraction to solve equations. ○ ... So, the value x = 4 is a solution of the equation x + 3 = 7.
