Question

(в+20)+63=150. 440-а×4=60

Answer 1

Пошаговое объяснение:
(в+20)+63=150
в=150-20-63
в=67

440-а×4=60
440-4а=60
-4а=60-440
-4а=-380
а=-380:(-4)
а=95

Answer 2

Let's solve the equations step by step:

1. (в + 20) + 63 = 150:

First, simplify the equation by combining like terms: в + 20 + 63 = 150 в + 83 = 150

Next, isolate the variable в by subtracting 83 from both sides: в + 83 - 83 = 150 - 83 в = 67

Therefore, the value of в is 67.

2. 440 - а × 4 = 60:

First, simplify the equation by performing the multiplication: 440 - 4а = 60

Next, isolate the variable а by subtracting 440 from both sides: 440 - 4а - 440 = 60 - 440 -4а = -380

To solve for а, divide both sides of the equation by -4: (-4а)/(-4) = (-380)/(-4) а = 95

Therefore, the value of а is 95.

So, в = 67 and а = 95 satisfy both equations.
