Question

21,3х–7,3–9,3х=90,02!!!!!!

Answer 1

$21,3x - 7,3 - 9,3x = 90,02 \\ 12x - 7,3 = 90,02 \\ 12x = 90,02 + 7,3 \\ 12x = 97,32 \\ x = 97,32 \div 12 \\ x = 8,11$

Answer 2

It seems like you've provided an equation for me to solve:

21.3x - 7.3 - 9.3x = 90.02

To solve for 'x', we can combine the 'x' terms on the left side of the equation and then isolate 'x' by performing the necessary arithmetic operations. Let's solve it step by step:

Step 1: Combine like terms on the left side: (21.3x - 9.3x) - 7.3 = 90.02 12x - 7.3 = 90.02

Step 2: Add 7.3 to both sides to isolate the 'x' term: 12x = 97.32

Step 3: Divide both sides by 12 to solve for 'x': x = 97.32 / 12 x = 8.11

So, the solution to the equation is approximately x = 8.11.
