Answer:
x = 4
x = 6
x = 7/2
Explanation:
Solve 5x + 2 = 22:
5x+2-2=22-2 (subtract 2 from both sides)
5x=20
x=4
Solve 2x-5=7
2x-5+5=7+5 (add 5 to both sides)
2x=12
x=6
Solve 2x+5=12
2x+5-5=12-5 (subtract 5 from both sides)
2x=7
x= 7/2
=> 5x + 2 = 22
=> 5x = 22 – 2
=> 5x = 20
=> x = 20/5
=> x = 4
=> 2x - 5 = 7
=> 2x = 7+5
=> 2x = 12
=> x = 12/2
=> x = 6
=> 2x + 5 = 12
=> 2x = 12-5
=> 2x = 7
=> x = 7/2
