T = Total
135+3x=T
25x+5x=T
After how many times will they pay the same amount? Please explain how <3
I'm assuming this is supposed to be :
25+5x=T
Since each equation equals T, we can just set them equal.....and we have
135 + 3x = 25 + 5x subtract 3x, 25 from both sides
110 = 2x divide both sides by 2
55 = x
