Slove the following expressions

Question

I have typed up six problems if you could show me how I have plenty of this algebra

 

31.5=a-34.4

x+76.32=164.89

36=a-64

96+y=187

x-9=26

x+23=92

Answer 1

31.5 = a - 34.4

add 34.4 to both sides:

a = 65.9

 

x + 76.32 = 164.89

subtract 76.32 from both sides:

x = 88.57

 

36 = a - 64

add 64 to both sides:

a = 100

 

96 + y = 187

subtract 96 from both sides:

y = 91

 

x - 9 = 26

add 9 to both sides:

x = 35

 

x + 23 = 92

subtract 23 from both sides:

x = 69
