Answer:
Step-by-step explanation:
3x - 2 + x + 8 = ( 9x + 7 - x + 5)/2
Add the like terms
4x + 6 = 8x + 12/2
Cross multiply or multiply both side by two
2(4x + 6) = 8x + 12
Use 2 to open the bracket
8x + 12 = 8x + 12
Collect like terms
8x - 8x = 12 - 12
0 = 0
Therefore, the equation has no solution
Answer:
It was a percentage increase of 15.15%
Step-by-step explanation:
