Question

Which line shows the first error in the solution?
(1) 6(x+2)=24
(2) 6x+12=24
(3) 6x=12
(4) x = 12 x 6
(5) x=72

Answer 1

line 4

it should be :
6(x + 2) = 24
6x + 12 = 24
6x = 12
x = 12/6
x = 2

Answer 2

Thanks

Answer 3

Answer 4

What is the correct solution to the equation?
4(x-3)=16

Answer 5

4(x - 3) = 16 --- distribute through the parenthesis
4x - 12 = 16 --- add 12 to both sides
4x = 16 + 12
4x = 28 --- divide both sides by 4
x = 28/4
x = 7

Answer 6

Which line shows the first error in the solution?

Three more than a number divided by 4 is –12. What is the number?
(1) x/4+3=-12
(2) x/4 +3 -3= -12-3
(3) x/4= -9
(4) x/4 x 4= -9 x 4
(5) x= -36
And thanks again for helping me
