Question

50-(х+3)=20 .. (97+у)+38=150....z-(180-3)=40....80+m-58=200......700-35-n=160.........k-250+3=40..... помогите решить уравнения!!!!!!!!!!!!!!

Answer 1

1)50-(х+3)÷20=50-20=30
30-3=27
50-(27+3)=20

Answer 2

To solve the given equations, let's go through each one step by step:

1. 50 - (x + 3) = 20 To solve this equation, we need to isolate the variable x. Let's simplify the equation: 50 - x - 3 = 20 47 - x = 20 Now, let's isolate x by subtracting 47 from both sides: -x = 20 - 47 -x = -27 Finally, multiply both sides by -1 to solve for x: x = 27

2. 38 + (97 + y) = 150 To solve this equation, let's simplify the expression inside the parentheses first: 38 + 97 + y = 150 135 + y = 150 Now, let's isolate y by subtracting 135 from both sides: y = 150 - 135 y = 15

3. z - (180 - 3) = 40 Let's simplify the expression inside the parentheses first: z - 177 = 40 Now, let's isolate z by adding 177 to both sides: z = 40 + 177 z = 217

4. 80 + m - 58 = 200 Let's simplify the equation: 80 + m - 58 = 200 22 + m = 200 Now, let's isolate m by subtracting 22 from both sides: m = 200 - 22 m = 178

5. 700 - 35 - n = 160 Let's simplify the equation: 665 - n = 160 Now, let's isolate n by subtracting 665 from both sides: -n = 160 - 665 -n = -505 Finally, multiply both sides by -1 to solve for n: n = 505

6. k - 250 + 3 = 40 Let's simplify the equation: k - 247 = 40 Now, let's isolate k by adding 247 to both sides: k = 40 + 247 k = 287

So, the solutions to the given equations are: x = 27 y = 15 z = 217 m = 178 n = 505 k = 287

I hope this helps! Let me know if you have any further questions.
