Question

Can u do 17-20 solve the equation please and show work

Answer 1

17. 4n-8=5
8+5=13
13/4=3.25
n=3.25

18. n/2+ 5=15
15-5=10
10*2=20
n=20

19. 5v-42=73
73+42=115
115/5=23
v=23

20. 3d-13=11
11+13=24
24/3=8
d=8

Hope I helped☺☺

Answer 2

Remember to follow PEMDAS: (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)
- Also follow the equality rule (what you do to one side you do to the other)

17) 4n - 8 = 5
4n - 8 (+8) = 5 (+8)
4n = 13
4n/4 = 13/4
n = 13/4 or 3.25

18) n/2 + 5 = 15
n/2+ 5 (-5) = 15 (-5)
n/2 = 10
n/2(2) = 10(2)
n = 20

19) 5v - 42 = 73
5v - 42 (+42) = 73 (+42)
5v = 115
5v/5 = 115/5
v = 23

20) 3d - 13 = 11
3d - 13 (+13) = 11 (+13)
3d = 24
3d/3 = 24/3
d = 8

hope this helps
