Answer: i don't think its possible for 20 to equal 5y and 25 the reason why is because for 5y to equal 20 y=4 that may be the answer but im not completely sure if it was supposed to be 20=x and 5y+25=x
Explanation:
if it was supposed to be 20=x and 5y+25=x the new equation would be 5y+25= 20 you then divide 5 from both sides. and get y=4
but if the equation was supposed to be x+5y=25 and x equals 20 then y would equal 1
