Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) 
= 9.5
3x+4 = 9.5(2)
3x = 19-4
x = 15/3
x = 5
b) 
= 5
7+2x = 5(3)
2x = 15-7
x = 8/2
x=4
Answer:
hi
Step-by-step explanation:
y=3x+24
y-3x=24
y-x= 24/3= 8
y-x = 8
2.
6x +6y= -24
6x+y= -24/6= -4
6x+y= -4
x+y= -4/6= -2/3
x+y= -2/3
First divide by 2
|x+1/4|=3
Then you pick the possible answers
|x+1/4|=3
|x+1/4|=-3
2 3/4 or -3 1/4
