The solution of the system of equation [tex]5x+2y = 29[/tex] ; [tex]x+4y =13[/tex] will be (3,2) and this can be determined by using the arithmetic operations.
Given :
[tex]5x+2y = 29[/tex] ----- (1)
[tex]x+4y =13[/tex] ----- (2)
Now, solve for x in equation (2).
[tex]x = 13-4y[/tex] --- (3)
Now, put the value of x obtained above in equation (1).
[tex]5(13-4y)+2y=29[/tex]
[tex]65-20y+2y=29[/tex]
[tex]36=18y[/tex]
[tex]y=2[/tex]
Now, put the value of y in equation (3).
[tex]x=13-(4\times 2)[/tex]
[tex]x=5[/tex]
