Can anyone do it? plz

Step-by-step explanation:

80 + x + 51 + 60 = 180

x = 180 - 80 - 51 - 60

substitute x=-11 back into the eq.

80 + x + 51 + 60 = 180

80 - 11 + 51 + 60 = 180

180 = 180  OK

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
