Answer:
Challenge #1:
Different examples:
2x+1=3x+2
4x+3=5x+4
3x+2=4x+3
Challenge #2:
Different examples:
2x+0=4x+1
3x+1=2x+5
6x+5=8x+6
Answer:
(-2x + 1 = 1x + 1) or (-4x + 2 = 2x + 2)
Step-by-step explanation:
f(x) = 6x + 9 ← in functional notation
let y = f(x) and rearrange the equation making y the subject
add 6x + 9 to both sides
y = 6x + 9
thus f(x) = 6x + 9
