6.4/8 = y/6 = x/7
0.8/1 = 4.8/6 = 5.6/7
6.4/8 = 4.8/6 = 5.6/7
x = 5.6 ; y = 4.8
I think that’s how you do it but not 100% sure
2/3(x + 7) = 10. Divide each side by 2/3.
x + 7 = 15. Subtract each side by 7.
x = 8
Answer: ( sorry if I’m wrong) 154
Step-by-step explanation:
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.
