Please solve each equation & check your solution. Thank You!

G) 1.2x + 3.3(2.4 - x) = 41
H) 3x/2 + 9/5 = 12
I) 5= 9/4 - r/3
J) 2(x - 2) = 12

Answer 1

G). 1.2x + 7.92 -3.3x = 41

-2.1x=33.08

x = 33.08/-2.1

x = - 15.752

H). 3x/2 + 9/5 = 12

Multiply through by 10

15x + 18 =120

15x =120-18

15x = 102

x =102/15

x=34/5

I). 5 = 9/4 - r/3

Multiply through by 12

60= 27 - 4r

60 - 27 = -4r

33 = - 4r

r = -33/4

J). 2(x - 2) = 12

2x - 4 = 12

2x = 16

x = 16/2

x = 8
