Question

5. What is the solution to the equation -2.5(x-4)=-3x+4?​

Answer 1

Answer: -12

Step-by-step explanation:

-(25/10)*(x-4)-(-3*x+4)=0                  

 (0 -  (5/2— • (x - 4))) -  (4 - 3x)  = 0  

 -5 • (x-4) - ((4-3x) • 2)/2 = x + 12/2

 x+12 /2 • 2 = 0 • 2

-12

 

Answer 2

Answer:

x = -12

Step-by-step explanation:

-2.5(x-4)=-3x+4

Distribute

-2.5x +10 = -3x +4

Add 3x to each side

-2.5x+10 +3x = -3x+4+3x

.5x +10 = 4

Subtract 10 from each side

.5x+10-10=4-10

.5x = -6

Divide by .5

.5x/.5 = -6/.5

x = -12
