4x+2y=4,x-3y=15 how would u substitute this equation for both?

By using the substitution method, the equation solved and get the values of x and y as x = 3 and y = - 4Step-by-step explanation:Given equations are:                    4 x + 2 y = 4         ……….(1)                     x - 3 y = 15         …………(2) Now, use the substitution method to solve the given two equations. Multiply equation 2 by 4 on both sides, we will get                      4 x - 12 y = 60     ……..(3) Now, subtract equation 1 from equation 3, we get              (4 x + 2 y) - (4 x - 12 y) = 4 - 60              14 y = - 56              y = - 4 Hence, from the above equation, we get the value of y. Now, we put the value of y in equation 2, we get                     x - 3(-4) = 15                     x + 12 = 15                     x = 3 Hence, the value of x and y by using the substitution method as,                               x = 3 and  y = - 4
