Solve for x:<br> -3(2x+1) + 3x = 6x + 3<br> Help!!
djverab [1.8K]

Answer:

b  x =-2/3

Step-by-step explanation:

-3(2x+1) + 3x = 6x + 3

Distribute

-6x -3 +3x =6x+3

Combine like terms

-3x-3 = 6x+3

Add 3x to each side

-3x+3x-3 = 6x+3x+3

-3 = 9x+3

Subtract 3 from each side

-3-3 = 9x+3-3

-6 = 9x

Divide by 9

-6/9 = 9x/9

-2/3 =x

Karolina [17]

Answer:

See below

Step-by-step explanation:

.50 x    + .18(40 - x)   =   .30 ( 40 )

.50 x   + 7.2 - .18x  =   12

.32x  = 4.8

x = 15 L of 50%     25 liters of 18%
