Add together all the numbers with the common variable leaving the constant at the end. 13t+12=64 Subtract 12 from both sides. 13t=52 Finally, divide by 13 to isolate the variable. t=4
Siamone has $65.32 + DAN Dan has CARLY - $37.50 CARLY = $127.75 Plug Carly into Dan's equation... $127.75 - $37.50 = $90.20 DAN = $90.20 Plug Dan into Siamone's equation $65.32 + $90.20 = $155.57
