The value of x and y in this system ofequationsis 5 and 6 respectively.Mathematically, anequationis a statement that asserts the equivalency of twoexpressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by anequalsign( =). The LHS and RHS can benumbers, variables, constants, or further complex fine expressions.Equations can be classified based on theirdegree, which corresponds to the highestpowerof the variables involved. For example, linear equations have a degree of 1, quadratic equations have adegreeof 2, and so on.Given thesystemof equations:3x + 2y = 45 ...(1)y = 3x ...(2)Substitute the value of y inequation(1) from equation (2),3x + 2(3x) = 453x + 6x = 459x = 45x =x = 5.Put this value of x inequation(2),y = 3(2)y = 6.So, thevalueof x and y are 5 and 6 respectively.Learn more aboutEquationshere:brainly.com/question/28953876#SPJ6...
