Question

А +156=17*20 В скобках 1604 минус У) -108 = 800

Answer 1

А)  а+156=17*20      17*20=340
а+156=340
а=340-156
а=184

б)  (1604-y)-108=800
1604-y=800+108
y=1604-908
y=696

Answer 2

А+156=17×20
а+156=340
а=340-156
а=184
-------------

Answer 3

To solve the equations, we need to find the values of variables A, B, and Y. Let's proceed step-by-step:

1. Equation 1: A + 156 = 17 * 20

First, let's simplify the right-hand side: 17 * 20 = 340

Now, isolate variable A on the left-hand side: A = 340 - 156 A = 184

So, the value of variable A is 184.

2. Equation 2: (A + 1604) - Y - 108 = 800

We already know the value of variable A from the previous equation, which is 184. Now we can substitute it into the equation: (184 + 1604) - Y - 108 = 800

Simplify the left-hand side: 1788 - Y - 108 = 800

Now, isolate variable Y on the left-hand side:

• Y = 800 - 1788 + 108
• Y = -880

To find the value of variable Y, we multiply both sides by -1: Y = 880

So, the value of variable Y is 880.

3. Equation 3: B (the equation is incomplete as it lacks an equals sign, so I will assume it is supposed to be an equation)

It is not clear what the equation is for variable B as it only shows a number in the parentheses. If you can provide the complete equation for B, I can help you solve for its value.

To summarize the solutions: A = 184 Y = 880

Please provide the complete equation for B if you need assistance with its value.
