Question

67 + a = 79 * 8 600 + y = 219 * 4 52 : x = 48 : 12 X + 230 = 450 + 210 + 70

Answer 1

1) 67+а=79*8
67+а=632
а=632-67
а=565

2) 600+у=219*4
600+у=876
у=876-600=276

3) 52:х=48:12
52:х=4
4х=52
х=13

4) х+230=450+210+70
х+230=730
х=730-230=500

Answer 2

Let's solve each equation step by step:

1. 67 + a = 79 * 8600

To solve for 'a', first, let's calculate the right side of the equation:

79 * 8600 = 678,800

Now, subtract 67 from both sides to isolate 'a':

a = 678,800 - 67 a = 678,733

So, the value of 'a' is 678,733.

2. y + 219 = 4 * 52

To solve for 'y', first, let's calculate the right side of the equation:

4 * 52 = 208

Now, subtract 219 from both sides to isolate 'y':

y = 208 - 219 y = -11

So, the value of 'y' is -11.

3. 52 : x = 48 : 12

To solve for 'x', we'll use the concept of ratios. Cross-multiply the terms:

52 * 12 = 48 * x

624 = 48 * x

Now, divide both sides by 48 to isolate 'x':

x = 624 / 48 x = 13

So, the value of 'x' is 13.

4. x + 230 = 450 + 210 + 70

To solve for 'x', first simplify the right side:

450 + 210 + 70 = 730

Now, isolate 'x' by subtracting 230 from both sides:

x = 730 - 230 x = 500

So, the value of 'x' is 500.
