Answer:

8.3recurring

Explanation:

0.2x+2.7x =2.9x

rewrite the questions

2.9x-8.1=6.9+1.1x

like terms together. Therefore:

2.9x-1.1x = 1.8x

8.1 will go to the other side of the equal sign. Therefore:

8.1+6.9 = 15

Therefore: 1.8x = 15

x =15/1.8 which is equal to 8.3recurring

0.2x + 2.7x - 8.1 = 6.9 + 1.1x

Combine like terms on left side:

0.2x + 2.7x = 2.9x

Now you have:

2.9x -8.1 = 6.9 + 1.1x

Subtract 1.1x from both sides:

1.8x - 8.1 = 6.9

Add 8.1 to both sides:

1.8x = 15

Divide both sides by 1.8:

X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3
