Question

(Х+67)*90=81 000. (Х+84)*42=23 520

Answer 1

х+67=900

х=900-67

х=833

х+84=560

х=560-84

х=476

Answer 2

To solve for the value of X in the equations you provided, we can set up a system of equations and solve for X. Here are the equations:

1. (X + 67) * 90 = 81,000
2. (X + 84) * 42 = 23,520

Let's solve for X one equation at a time:

1. (X + 67) * 90 = 81,000

First, divide both sides by 90 to isolate (X + 67):

(X + 67) = 81,000 / 90 (X + 67) = 900

Now, subtract 67 from both sides to solve for X:

X = 900 - 67 X = 833

So, the solution to the first equation is X = 833.

Now, let's solve the second equation:

2. (X + 84) * 42 = 23,520

Divide both sides by 42 to isolate (X + 84):

(X + 84) = 23,520 / 42 (X + 84) = 560

Subtract 84 from both sides to solve for X:

X = 560 - 84 X = 476

So, the solution to the second equation is X = 476.

Therefore, the values of X that satisfy both equations are:

X = 833 (from the first equation) X = 476 (from the second equation)
