Consider the equations 4(x-3)=16 and 4x-3=16 do they have the same solution? Why or why not ?

1 answer:

4 0

Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation

Solution:

4 (x-3)=16

4x - 12 = 16

4x = 16 + 12

4x = 28

x = 7

4x - 3 = 16

4x = 16 + 3

4x = 19

x = 19/4

x = 4.75

If 3(2x) - 4(3x) + 3 = 0. Find the possible values of x pls help

IRISSAK [1]

Answer: x=1/2=0.5

Step-by-step explanation:

Given

3(2x) - 4(3x) + 3= 0

Expand parenthesis

6x - 12x + 3 = 0

Combine like terms

-6x + 3 = 0

Subtract 3 on both sides

-6x + 3 - 3 = 0 - 3

-6x = -3

Divide -6 on both sides

-6x / -6 = -3 / -6

x = 1/2 = 0.5

Hope this helps!! :)

sukhopar [10]

Answer:

m = -18

Step-by-step explanation:

Step 1: Combine like terms

-8 = -m + 2m + 10

-8 = m + 10

Step 2: Subtract 10 from both sides

-8 - 10 = m + 10 - 10

-18 = m

Answer: m = -18
