Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34
7) 7/8
8) 13.5%
9) 3/25
10) 150%
11) 1/4
12) 2/3
13) .31
14) 17/20
15) .81
16) 1.4
First one is
J-5=61
+5. +5
J= 66
3x4= 12+2= 14 (the dot means multiplication) and i dont know further srry :(
