note: 3x means 3 times x or x+x+x xx means x times x or x(x)
so x+5+x+x+x+x+x+5=x+x+6+x+x add like terms 6(x)+10=4(x)+6 not sure about the 0-9 part so I will disreagrd for now, please ask for correction later
6x+10=4x+6 subtract 4x from both sides 2x+10=6 subtract 10 from both sides 2x=-4 divide both sides by 2 x=-4/2=-2 (divide or multiply by different signs and get negative) x=-2
