Question

need to know as well o.2 (d - 6) = 0.3d + 5 - 3 + 0.1d for the answer please!!!

Answer 1

The first step is to factor

(3)(0.5x)- (3)(4)= 2x+2

 

step 2= 1.5x-12=2x+2

 

step 3= 1.5x-12+12= 2x+2+12

 

step 4= 1.5x= 2x+14

 

step 4= 1.5x- 2x= 2x-2x +14

 

step 5= -0.5x= 14

 

step 6= -0.5x/-0.5= 14/-0.5

 

step 7: x= -28 which is answer D
