Question

va rog x:9+9x9-9=100-5x5+2

Answer 1

x:9+81-9=100-25+2

x:9+81-9=77

x:9+81=77+9

x:9=86-81

x:9=5

x=5x9

x=45

Answer 2

$x \div 9 + 9 \times 9 - 9 = 100 - 5 \times 5 + 2$

$x \div 9 + 81 - 9 = 100 - 25 + 2$

$x \div 9 + 72 = 75 + 2$

$x \div 9 + 72 = 77$

$x \div 9 = 77 - 72$

$x \div 9 = 5$

$x = 5 \times 9$

$x = 45$
