Step-by-step explanation:
You have to substitute a by 17 and then just subtract.
Answer:
1. x+2=2x+1 5. 8+x=3x
2-1=2x-x 8 =3x-x
1=x or x=1 8=2x
x=4
2. 2x+7=3x+4 6. 3x+6=6x
2x-3x=4-7 3x-6x=-6
-x=-3 -3x=-6
x=3 x=2
3. 2x-5=x-7. 7. 3x+3=x-5
2x-x= -7+5 3x-x= -5-3
x= -2 2x=-8
x=-4
4. x+6=3x-2 8. 2x+5=4x-1
x-3x= -2-6 2x-4x= -1-5
-2x=-8 -2x= -6
x=4 x=3
4/100= 0.04
25/1000= 0.025
