Question

Four plus three times a number is twice the number what is the number A. -⅘ B. -3/2 C. 0 D. -4

Answer 1

To solve the equation, "four plus three times a number is twice the number," we can use algebraic notation. Let's call the unknown number "x."

The equation can be written as:

4 + 3x = 2x

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 2x from both sides of the equation:

4 + 3x - 2x = 2x - 2x

Simplifying the equation gives us:

4 + x = 0

Next, we can isolate x by subtracting 4 from both sides of the equation:

4 + x - 4 = 0 - 4

Simplifying further, we get:

x = -4

Therefore, the number that satisfies the equation is -4.

Answer 2

D

Explanation:

let the number be n , the 3 times the number is 3n and 4 plus (add) this is

4 + 3n

this is equal to twice the number 2n, the equation is then

4 + 3n = 2n ( subtract 2n from both sides )

4 + 3n - 2n = 2n - 2n ( simplify both sides )

4 + n = 0 ( subtract 4 from both sides )

4 - 4 + n = 0 - 4 , that is

n = - 4

the number is then - 4
