Which is the simplified form of the expression 3(7/5x + 4) - 2(3/2 - 5/4x)? 1) -39/5x - 11/2
2)67/10x + 9
3) 3/10x + 5/2
4) 15 + 76/10x

(67/10)x + 9 (answer [2])

Step-by-step explanation:

3(7/5x + 4) - 2(3/2 - 5/4x). after the indicated multiplication has been carried out, is:

(21/5)x + 12 - 3 + (5/2)x

Combining like terms, we get (4.2 + 2.5)x + 9, or

6.7x + 9, or (67/10)x + 9 (answer [2])

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
