Question

57 + t = 8×9 71-z=7×6​

Answer 1

Пошаговое объяснение:

57 + t = 8 * 9

57 + t = 72

t = 72 - 57

t = 15

71 - z = 7 * 6

71 - z = 42

z = 71 - 42

z = 29

Answer 2

Let's solve these equations:

1. 57 + t = 8 × 9 First, calculate the right side of the equation: 8 × 9 = 72. Now, to solve for t, subtract 57 from both sides: t = 72 - 57 t = 15

2. 71 - z = 7 × 6 First, calculate the right side of the equation: 7 × 6 = 42. Now, to solve for z, subtract 42 from 71: 71 - 42 = 29 z = 29

So, the solutions are:

1. t = 15
2. z = 29
