Question

2×+6=5 ;6-3×=4 ; ×+1=2(×+2);
(×-1)*3=×+2.

Answer 1

2x+6 = 5
2x = 5-6
2x = -1
x = -1/2.

6-3x = 4
-3x = 4-6
-3x = -2 /•(-1)
3x = 2
x = 2/3.

x+1 = 2(x+2)
x+1 = 2x+4
x-2x = 4-1
-x = 3
x = -3.

(x-1)•3 = x+2
3x-3 = x+2
3x-x = 2+3
2x = 5
x = 5/2.



I hope I helped you :)

Answer 2

2x+6=5
2x=5-6
2x=-1
X=-1/2
6-3x=4
-3x=4-6
-3x=-2/×(-1)
3x=2
X=2/3
X+1=2(x+2)
X+1=2x+4
X-2x=4-1
-X=3/×(-1)
X=-3
(X-1)×3=x+2
3x-3=x+2
3x-x=2+5
2x=7
X=7/2
