9(9x)+762/3=11x-(49-23) is now
9(9x)+762/3=11x-26 due to solving the parenthesis, and then
81x+762/3=11x-26 due to distributive property, which becomes
81x+254=11x-26 due to division, which becomes
70x+254=-26 due to subtraction of 11x from both sides, wchich becomes
70x=-280 due t o subtraction of 254 from both sides, which becomes
x=-4 due to division of both sides by 70

9(9x) + 762/3 = 11x - (49-23)
81x + 762/3 = 11x - (26)
81x +254 = 11x-26
81x-11x+254 = -26
70x = -26-254
70x = -280
x = -280/70
Therefore x = -4
