Question

X+78=9*9 y-43=8*7 57+t=8*9 71-z=7*6

Answer 1

Ответ:

X+78=9×9

X+78=81

X=81-78

X=

y-43=8×7

y-43=56

y=56+43

y=99

57+t=8=8×9

57+t=72

t=72-57

t=15

71-z=7×6

71-z=42

z=71-42

Z=

Answer 2

Let's solve each of these equations:

1. x + 78 = 9 * 9 First, calculate 9 * 9: 9 * 9 = 81 Now, subtract 78 from both sides to isolate x: x = 81 - 78 x = 3

2. y - 43 = 8 * 7 First, calculate 8 * 7: 8 * 7 = 56 Now, add 43 to both sides to isolate y: y = 56 + 43 y = 99

3. 57 + t = 8 * 9 First, calculate 8 * 9: 8 * 9 = 72 Now, subtract 57 from both sides to isolate t: t = 72 - 57 t = 15

4. 71 - z = 7 * 6 First, calculate 7 * 6: 7 * 6 = 42 Now, add 42 to both sides to isolate z: z = 71 - 42 z = 29

So, the solutions to the equations are:

1. x = 3
2. y = 99
3. t = 15
4. z = 29
