Hey there!
“2x + 1 = 23”
SUBTRACT by 1 to BOTH SIDES
2x + 1 – 1 = 23 – 1
CANCEL out: 1 – 1 because it gives you the value of 0
KEEP: 23 – 2 because it helps us solve for x
“23 – 1 = 22”
NEW EQUATION: 2x = 22
DIVIDE by 2 to BOTH SIDES
2x/2 = 22/2
CANCEL out: 2/2 because that gives you 1
KEEP: 22/2 because it helps us solve for x
Answer: x = 11 ☑️
Good luck on your assignment and enjoy your day!
