This month erica saved $20 more than last month. for the two months, she saved a total of $70. how much did she save each month?

So it would be. let x be the total money she saved last year so it would be
20+x+x=70
then
20+2x= 70
then
2x=50
x= 25

so the money she saved this month is 20+25= 45
and the money she saved last month was 25

hope it helped :)Pls mark the brainliest. pls
