Question

Exercise 7.2
Solve the following equations and check your result,
1. 37-18=7-27
A. 0.6y = 0.5y + 25
3. 4(3y – 3) – 2(3y – 5) = 7
4.5x-3-38-9​

Answer 1

Answer:

37-18=7-27=>19=-20

0.6y =0.5y+25

0.1y=25

y=250

4 (3y-3)-2 (3Y-5)

12y-12-6¥+10=6¥=22-7 =6y=10

y=5/2

5x-3-38-9=5x-50 x= 10
