Four more than twice a number is 8
1 answer:
let x is the number
twice a number is 2x
Four more than twice a number: 2x + 4
Four more than twice a number is 8 :
2x +4 = 8
If solve for x then
2x + 4 = 8
subtract 4 to both sides
2x +4 - 4 = 8 -4
Simplify
2x = 4
Divide both sides by 2
2x/2 = 4/2
Simplify
x = 2
