1.2x + 3 =4x + 2 how many solutions does the equation have? 2.10p+5= 18p-6/2 what is the value of p? 3.a-2= 3+6a/3 what is the value of a? 4.5+r-2=9 what is the value of r? 5.0.61m-1.51m =9 what is the value of m? 6.-2(x+1/4) +1 =5 solve for x 7.6f - 12 = -4f +6 what is the value of f? 8.3n + 16 =7n what is the value of n? 9.1/3m + 3 - 5/6m = -15 what is the value of m?

1. 2x+3=4x+2
  ⇒ 4x-2x=3-2
2x=1
x=1/2
There is one solution.

2. 18p-10p=5+6/2
8p=5+3
8p=8
p=8:8
p=1

3. 6a/3=2a
2a-a= -2 -3
a= - 5

4. 5+r-2=9,
 5-2+r=9
3+r=9
r=9 - 3
    r=6

5. -0,9 m= 9
     m= - 10

6. -2 (x+1/4)=5-1=4
     x+1/4= -2
     x= -2 - 1/4
     x= -8/4 - 1/4= - 9/4

7. 6f+4f= 6 + 12
    10 f = 18
      f=18/10=1,8

8. 7n - 3n= 16
    4n=16
    n=16:4
    n=4

9. 1/3m-5/6m= - 15 - 3
     2/6 m-5/6=-18
     - 3/6m=-18  ⇒ 1/2m=18
       m=2*18=36
     

Idon’t exactly understand but i think dbc=rst
