9. 7x-9 = 16​

Answer 1

Answer:

SOL:

Step-by-step explanation:

1) x-2=7

X=7+2

x=9

2) y+3=10

y=10-3

y=7

3) 6= Z+2

6-2=Z

4= Z

6) t/5=10

t = 10×5

t = 50

5) 6x=12

x= 12/6

x= 2

7) 2x/3= 18

2x= 18× 3

2x= 54

x = 54/2

x= 27

8) 1.6= y/1.5

1.6× 1.5=y

2.4=y

9) 7x - 9=16

7x= 16+9

7x = 25

x= =3.5714285714

4) 3/7 + x= 17/7

x =17/7 - 3/7

x=(17-3)/7

x = 14/7

x =2
