What value of x makes this equation true? 4x – 10 = 18

Sagot :

4x-10=18
4(7)-10=18
28-10=18
so the value of x is 7

4x - 10 = 18
add 10 to both sides of the equation
4x - 10 + 10 = 18 +10
4x + 0 = 28
4x = 28
divide both sides with 4
4x/4 = 28/4
x = 7
you can always apply this concept when dealing with linear equations with one variable.
