What is the equation 4x+8=
As Always True/Infinite Solutions
True for one value/One Solution
And true for no value/No Solution

Step-by-step explanation:

1-by balancing method

4x=8

So we divide by 4 in both sides to remove 4 to get the value of x

4x/4=8/4

So,now solve it

x=2

Put the x in place to check the answer

4×2=8

2-by transposing method

4x=8

In this method we transpose the 4 to RHS and in RHS the number in multiply changes in divide

so this is written as

x=8/4

Now solve it

x=2

Now check

4×2=8

hope this helps

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
