7x - 4y = 80
3x - 4y = -80
Ram's salary increases by 20% and decreases by 10% to Rs 7200 then what will be his initial salary?
3x + 2y = 54
2x - 2y = 16
if a = 6-√35 find the value of a^2 + 1/a^2
x - 2y = 8
x - 3y = 3
If Ram's salary is Rs 7200 when increased by 20% & decreased by 10% what was his initial salary?
