#color(indigo)("variable " = x#

#color(indigo)("Coefficient of variable "= 2#

#color(indigo)(7, 360 " are the constants"#

#"Let Time taken by Tom be " x#

#"Time taken by Lydia " = x + 7 " min."#

#"Total time taken by both " = x + x + 7 = 2x + 7 " min."#

#"But given total time taken as " 6 hrs ' or " = 360 "min."#

#:. 2x + 7 = 360 " min."#

#color(indigo)("variable " = x#

#color(indigo)("Coefficient of variable "= 2#

#color(indigo)(7, 360 " are the constants"#
