Answer 2

x + 3.0014 = 13.551

just subtract both sides by 3.0014
x = 13.551 - 3.0014 = 10.5469
answer is C

18.099x = 77.8257
now you devide both side by 18.099 to solve for x
x = 77.8257/18.099 = 4.3
answer is C

3(x - 1.3) = 9.3
you have to distribute by multiplying 3 to both x and 1.3
3x - 3.9 = 9.3
add 3.9 to both sides
3x = 13.2
lastly divide 3 both sides
x = 13.2/3 = 4.4
answer is A

4x + 6.4 = 2x - 6
since 4x and 2x are common.. you can move subtract 2x from both side and 6.4 from both sides
4x - 2x = -6 - 6.4
2x = -12.4
divide by 2 fro both sides
x = -6.2
answer is C

Answer 3

1. c. 10.5496
13.551-3.0014=x

2. c. 4.3
77.8257/18.099=x

3. a. 4.4
9.3/3, then
3.1+1.3

4. c.-6.2
move 2x to the other side
2x+6.4=-6, then move the 6.4 to the otherside
2x=-12.4, then
-12.4/2

Answer 4

Solving for X?
