Question

State the missing steps and reasons to this solution of 3(x+4)=18
a) 3(x+4)=18
b) Distributive property
c) 3x+12-12=18-12
d) 3x+0=18-12
e) 3x=18-12
f) Simplify
g) 3x/3= 6/3
h) 1x=6/3
i) x=6/3
j) x=2

Answer 1

hint: the distributive property is a*(b+c) = a*b + a*c

Answer 2

For b it would be 3x+4=18.

Answer 3

close

Answer 4

c?

Answer 5

B would be
3*x + 3*4 =18 but simplified

Answer 6

yes or 3x + 12 = 18

Answer 7

is this 4 a test @AppleBVB

Answer 8

No, this is not for a test.

Answer 9

For c it would be to subtract 12 from both sides. For g it would be to divide by 3. I dont know what to do for d, e, h, i, and j.

Answer 10

No, this is for a test; this is just a warm up problem from school.

Answer 11

D is just showing that once you subtract 12, there's 0 left to add to 3x
E is just taking away 0 as a place holder
H they are just showing that 3x/3 is equal to 1x
I is taking away one since it's unnecessary to write it
J is the final answer when 6 is divided by 3

Is that what you were needing??
