Best ResponseYou've already chosen the best response.0@hba that will only give one solution this should give two since we will have f=a where a is positive f=a means f=a or f=a

Best ResponseYou've already chosen the best response.0Great now you have\[\left 9x+4 \right = 7\]One solution is when the quantity (9x+4) is positive, so solve\[9x+4=7\]The other solution is when the quantity (9x+4) is negative. So, solve\[\left( 9x+4 \right)=7\]Then you'll have the complete solution
