It costs $0.07 to send a text message and $0.12 to send a picture on your cell phone. You spend $3.38 and send twice as many text messages as pictures. How many text messages did you send?

    best would be to create a formula that represent text messages t picture messages p and you need to find out how much you spend = x and input the numbers into the formula

    0.07*(2x)+ 0.12*x = 3.38

    0.07*(2x)+ 0.12*x=3.38 0.14*x+0.12*x=3.38 0.26x=3.38 x=?
