Question 51154: how do you write an equation for this function
the output is 5 more than 2 times the input.find the input when the output is 17

say the input is "x"(cuz input is variable)
so we will build up the equation
so the out put is 5 more than 2times the input,
therefore 2 times input, means 2x and 5 more, means 5 should be added with the 2 times input
therfore we get the equation 2x+5 = output.
Cheers we hav come up with the equation. So substitude this equation in the question.
2x+5= output
therefore 2x+5=17
2x= 17-5
x= 12/2
= 6
