Answer :
Product of 4 and a number = 4x
'is' is an equal sign
18 more than twice the number = 2x + 18
So we have:
4x = 2x + 18
Subtract 2x to both sides:
2x = 18
Divide 2 to both sides:
x = 9
'is' is an equal sign
18 more than twice the number = 2x + 18
So we have:
4x = 2x + 18
Subtract 2x to both sides:
2x = 18
Divide 2 to both sides:
x = 9
