Question

(270-х)-46=56522-(х-25)=42(135-х)+45=67​

Answer 1

(270 - х) - 46 = 56                           522 - (х - 25) = 42

270 - х = 56 + 46                            х - 25 = 522 - 42

270 - х = 102                                   х - 25 = 480

х = 270 - 102                                   х = 480 + 25

х = 168                                             х = 505

--------------------------------------------------------------------------------

(135 - х) + 45 = 67

135 - х = 67 - 45

135 - х = 22

х = 135 - 22

х = 113

Answer 2

Let's solve the equations step by step:

Equation 1: (270 - x) - 46 = 56522 - (x - 25) Let's simplify both sides of the equation: 224 - x = 56522 - x + 25

We can eliminate the -x term on both sides by adding x to both sides: 224 = 56547 - x

Now, let's isolate x by subtracting 56547 from both sides: x = 56547 - 224 x = 56323

So the solution to Equation 1 is x = 56323.

Equation 2: 42(135 - x) + 45 = 67 Let's simplify the equation: 5670 - 42x + 45 = 67

Combine like terms: 5715 - 42x = 67

Now, let's isolate -42x by subtracting 5715 from both sides: -42x = 67 - 5715 -42x = -5648

Finally, divide both sides by -42 to solve for x: x = (-5648) / (-42) x = 134

So the solution to Equation 2 is x = 134.

Therefore, the solutions to the given equations are x = 56323 and x = 134.
