2.7x + 6.1 + 3.2x -4.9

=> (2.7x +3.2x) + (6.1 - 4.9)

=> 5.9x + 1.2

-0.3 (x - 4) + x = 0.5 (3 - x)

=> -0.3x + 1.2 + x = 1.5 - 0.5x

=> 1.2x = 1.5 - 1.2 = 0.3

=> x = 0.3/1.2 = 1/4 = 0.25

a/2.7x+6.1+3.2x-4.9=(2.7+3.2)x+(6.1-4.9)=5.9x+1.2

b/-0.3(x-4)+x=0.5(3-x)

<->-0.3x+1.2+x=1.5-0.5x

<->-0.3x+x+0.5x=1.5-1.2

<->(-0.3+1+0.5)x=0.3

<->1.2x=0.3

<->x=0.3/1.2=0.25

Please pay attention in class tomorrow so you can at least try to finish your homework on your own.

If it helps, just multiply everything by 10 and then solve. Decimal problem will be solved.
