Question

1) 3+2(x-1)=17 2)2x+3x=20 3)8x+5-4x=41. 4)2(x+5)=28 5) 3(x+2)-2x=10 6)5(x+3)+2(x+3)=56​

Answer 1

1$3 + 2(x - 1) = 17 \\ 2(x - 1) = 17 - 3 \\ 2(x - 1) = 14 \\ x - 1 = 14 \div 2 \\ x - 1 = 7 \\ x = 7 + 1 \\ x = 8$

2) 2x+3x=20

5x=20

x=20:5

x=4

3) 8x+5-4x=41

8x-4x=41-5

8x-4x=36

4x=36

x=36:4

x=9

4) 2(x+5)=28

x+5=28:2

x+5=14

x=14-5

x=9

Answer 2

1) 3+2x -2 =17. 1 +2x=17. 2x =17-1 2x =16. X =8
2) 5x =20. X=4
3) 4x+5 =41. 4x =41 -5. 4x =36. X=9
4)x+5=14. X=14-5. X=9
5) 3x +6-2x =10. X+6 =10. X=10-6. X=4
6) (5+2)x(x+3)=56. 7(x+3) =56. X+3=8 X=8-3. X=5
