Question

in the equation 8x - 1 = 3x + 4 the variable x represents the same value. Which value of x is the solution of the equation; x = 0, 1, 2, or 3? Explain.

Answer 1

8x-1=3x+4Move the variable to the left side and change its sign and you should get 8x1-3x=4

And then move the consistent to the right side and change the sign and you should get 8x-3=4+1

now you should have 8x-3x=4+1 now collect like terms and you should get 5x=4+1

Add the numbers And you should get 5x=5 divide both sides by 5 and you should get x1

Answer 2

Given the following expression:

a.) 8x - 1 = 3x + 4

Let's determine the value of x,

8x - 1 = 3x + 4

8x - 1 + 1 - 3x = 3x + 4 + 1 - 3x

8x - 3x = 4 + 1

5x = 5

5x/5 = 5/5

x = 1

Therefore, x = 1.
