Solve for x: 10x+18 = 8x+4

x= -7

Step-by-step explanation:

subtract 8x from both sides of the equation which would leave you with 2x+18=4

then you would subtract 18 from each side of the equation leaving you with 2x= -14

the divide by 2 on both sides of the equation giving you the answer of

x= -7

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..

i believe the correct answer is b.
