Step-by-step explanation:
3x-23=5
1.Add 23 to both sides of the equation
3x-23+23 =5+23
2. add the numbers
3x=28
3.divide both sides by 3
3x=28
3x/3 = 28/3
4. cancel the term that are in numerator and denominator.
final answer is x=28/3.

Answer:
Step-by-step explanation:
1) 3x - 23 = 5
3x = 5 + 23
3x = 28
x = 28/3
Verification : 3 ( 28/3 ) - 23
= 28 - 23
= 5
2) y + 1.1 = 6.9
y = 6.9 - 1.1
y = 5.8
Verification : 5.8 + 1.1 = 6.9
3) 9x + 10 = ( - 56 ) - 2x
9x + 2x = - 56 - 10
11x = - 66
x = - 66 / 11
x = - 6
Verification : 9 ( - 6 ) + 10 = ( - 56 ) - 2 ( - 6 )
- 54 + 10 = - 56 + 12
- 44 = - 44 .
4) 0.3x + 0.03 = 3
0.3x = 3 - 0.03
0.3x = 2.97
x = 2.97 / 0.3
x = 9.9
Verification : 0.3 ( 9.9 ) + 0.03
= 2.97 + 0.03
= 3
5) 5x + 7 = 3x + 2
5x - 3x = 2 - 7
2x = - 5
x = - 5 / 2
Verification : 5 ( - 5 / 2 ) + 7 = 3 ( - 5/2 ) + 2
- 25 / 2 + 7 = - 15 / 2 + 2
( - 25 + 14 ) / 2 = ( - 15 + 4 ) / 2
- 11 / 2 = - 11 / 2.
