Question

Solve for the variable in each equation and then, check the result.
6. 5n-1=9
7. 3(3z-2)=12
8. x/4+1=5
9. 7a+3=10
10. ((m-5))/5=7

Answer 1

Answer:

2

Step-by-step explanation:

5n-1=9

5n=9+1

5n=10

n=10/5

n=2

Answer 2

Answer:

6. 5n-1=9

5n=9+1=10

5n=10

n= 10/5 =2

n=2

please make as briliant

9. 7a+3=10

7a=10-3=7

7a=7

a= 7/7=1

a =1

8. x/4+1=5

x/4=5-1=4

x/4=4

four is cancel

x=1

7. 3(3z-2) = 12

9z -6 = 12

9z=12+6 = 18

z=18/9= 2

z= 2

10. ((m-5))/5=7

m-5=7 multiple of 5

m=35+5=40

m=40
