What is the value of x in the following equation?
2 answers:
4x+8=20
First subtract 8 from both sides
4x+8=20(8-8 and 20-8)
4x=12
Now divide 4 from both sides
4x=12(4x/4 and 12/4)
x=3
So x= 3
Now time to check the equation.
4(3)+8=
Multiply 4 and 3
12+8=20
now add 12 and 8
So the answer is C. 3
20-8=12
12/4=3
4x3+8=20
Answer is c.
