Solve the equation

15.3 + 15 + 15.4 + 15.7 + x /5 = 15.4

thankyou

I suspect you mean...

(15.3 + 15 + 15.4 + 15.7 + x) /5 = 15.4

multipy both sides by 5.
15.3 + 15 + 15.4 + 15.7 + x = 15.4 *5
then subtract the four numbers on the left from both sides.

To solve the equation, we need to isolate the variable "x" on one side of the equation. Let's go through the steps one by one.

Step 1: Remove any parentheses or brackets (there are none in this equation).

Step 2: Simplify any divisions or multiplications (there is a division in this equation).

The equation is: 15.3 + 15 + 15.4 + 15.7 + x / 5 = 15.4

Since the division comes before addition, we should divide each term by 5 on the left side of the equation:

3.06 + 3 + 3.08 + 3.14 + x / 5 = 3.08

Step 3: Combine like terms by adding or subtracting (on the left side of the equation).

3.06 + 3 + 3.08 + 3.14 = 12.28

So the equation becomes: 12.28 + x / 5 = 3.08

Step 4: Isolate the variable "x" by performing the inverse operation (subtracting 12.28 from both sides of the equation).

12.28 + x / 5 - 12.28 = 3.08 - 12.28

The equation simplifies to: x / 5 = -9.20

Step 5: Finally, solve for "x" by multiplying both sides of the equation by 5.

5 * (x / 5) = -9.20 * 5

The equation becomes: x = -46

Hence, the solution to the equation is x = -46.
