1.2x + 3 =4x + 2

Dmitry_Shevchenko [17]

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
