Y=4x-1
3x+2y=13
solve system of equations

x= 15/11

y= 29/15

Step-by-step explanation:

Here, y=4x-1(i)

3x+2y =13(ii)

Putting value of y in equation ii)

or, 3x + 2(4x-1) =13

or, 3x+8x-2 =13

or, 11x =15

On solving

x = 15/11

Again, putting value of 'x' on equation i)

y = 4x(11/15) -1

=44/15 -1

= 29/15

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

first one because it can't have a fraction in it
