Answer:

c = 5

Step-by-step explanation:

c/6 - 4/9 = 7/18

Make denominators equal.

3c/18 - 8/18 = 7/18

Cancel denominators since they are equal.

3c - 8 = 7

Add 8 to both sides.

3c = 7 + 8

3c = 15

Divide 3 into both sides.

c = 15/3

c = 5

Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7
