Xavier and madeline’s age combined is 28. xavier is 4 yrs older than half of madeline’s age. how old will xavier be in 2 yrs?

14 years old

Step-by-step explanation:

let x= Xavier’s age

let y= Madeline’s age

Use linear function:

x+y=28

x=1/2y + 4

x+y=28

x-1/2y=4

Multiply 2nd equation by 2

x+y=28

2x-y=8

Add

3x=36

x=12

12+2=14

y=16

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..
