Step-by-step explanation:
<u>Step 1: Define</u>
35 + 0.8x = 43 - 7x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
- [Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
- [Division Property of Equality] Divide 7.8 on both sides: x = 1.02564

Answer:
The number of teacher who joined the school is 20
Step-by-step explanation:
Teacher : Students = 1 : 16
Number of teachers = 1x
Number of students = 16x
16x = 1600
x = 1600/16
x = 100
Number of teachers at the beginning = 100
Now, after some teachers (let it be y) joining the school,
Teacher : students = 3:40
The number of teacher who joined the school is 20
