Substitution means solving one equation for x or y then plugging it into another equation. Though I would use the elimination method for both of these systems. For the first system, multiply (5x+3y=25) by 2 and you will get 10x+6y=50. Then u can cancel out the 10x and 10x. In the second system, multiply 3

ok eq 1) (5x+3y=25) * 2= 10x + 6y =50 eq 2) 10x + 6y = 20 the 10x and the 10x cancel out to zero. as well as the 6y and the 6y.
