Answer 1

Answer:

3.16 4.37,38,39

Step-by-step explanation:

3.x*5=80 5x=80 x=16

4.x+x+1x+2=114

3x+3=114

3x=114-3=111

3x=111

x=111/3=37

x=37 37+1=38 37+2=39

Answer 2

Answer:

3. let the number be x

thus, 5x=x+80

5x-x=80

4x=80

x=80/4

x=20

therefore, the number is 20

4. let the first number be x

thus, second number is x+1

third number is x+2

thus, x+ x+1 +x+2=114

=x+x+x+1+2=114

=3x+3=114

3x=114-3

3x=111

x=111/3

x=37

therefore, the numbers are 37, 38 and 39
