Question

X+94=99, y-80=21, 67-x=30 как решить правельно

Answer 1

X=99-94 y=21+80 X=30-67

X=5 y =101 X=-33

Answer 2

To solve these equations, you need to find the values of the variables x and y that satisfy the equations. Let's solve them step by step:

1. X + 94 = 99: To find the value of x, you need to isolate x on one side of the equation. First, subtract 94 from both sides to get x alone on one side:

X + 94 - 94 = 99 - 94 X = 5

So, the value of x is 5.

2. Y - 80 = 21: To find the value of y, you need to isolate y on one side of the equation. First, add 80 to both sides to get y alone on one side:

Y - 80 + 80 = 21 + 80 Y = 101

So, the value of y is 101.

3. 67 - x = 30: To find the value of x, you need to isolate x on one side of the equation. First, subtract 67 from both sides to get x alone on one side:

67 - x - 67 = 30 - 67 -x = -37

Now, to solve for x, divide both sides by -1:

x = -37 / -1 x = 37

So, the value of x is 37.

To summarize, the correct solutions are: x = 5 y = 101 x = 37
