The true equations of the given questions are equation 1 and equation 2
To determine if the following equations are true;
1.

80/16 = 10 -4 -1
5 = 10 - 5
5 = 5
The equation is true because the left side and the right side are equal.
2.

36 - 4 = 4 + 7 * 4
36 - 4 = 4 + 28
32 = 32
The equation is true
3.

54 + 6 + 9 = 4 + 16
69 = 20
This equation is false because the left side and the right side are not equal.
4.

19 - 10 = 3.233 - 9
9 = -5.767
This equation is false because the left side and the right side are not equal.
Therefore,the true equation are equation 1 and equation 2
