Let x = the unknown number
five more than a number = twice the number
x + 5 = 2x
5 = 2x - x
5 = x
( Balance method is used to solve )
substitution
x + 5 = 2x
5 + 5 = 2 x 5
10 = 10
answer : the unknown number is 5
"more" means added to, or addition. So 8 more than 'x' is:
x + 8
X axis (-40,0)
y axis (0,15)
