True or False
x= 2 is a solution of the equation 7x + 4 = 18
If take 7 * 2 (since x=2) which gives me 14
Then if I add 14 to 4 which would get me 18
So my answer would be true

true. to prove this
7x + 4 = 18
u move the 4 to the other side of the equation
7x +4 (-4) = 18 (-4)
7x = 14
divide each side by 7
7x/7 = 14/7
x=2

you are very right
7x+4=18
7x+4-4=18-4
7x=14
divide 7x and 14 with 7
x=2
