`9x=(20+50)` e3w222222

To solve the equation 9x = (20 + 50), we first simplify the right side of the equation:

20 + 50 = 70

Now, we can rewrite the equation:

9x = 70

Next, we need to isolate x. To do this, we divide both sides of the equation by 9:

x = 70 / 9

When we perform this division, we find:

x = 7.777... (which can also be expressed as 7 and 7/9 or approximately 7.78 when rounded to two decimal places).

So, the solution to the equation is:

x = 70/9 or approximately 7.78.

This step-by-step explanation details how we simplified the equation and solved for x, ensuring we followed algebraic principles.
