How to solve this problem i don't know what to do

1) y=3

2)x =38

3)m = 3

4)h=21

Step-by-step explanation:

Here are some equations given from which we have to find the values of the variables by using the simple techniques of mathematics. We will start From the very first to the last part

1)

The given equation is

y+2 = 5

We have to find y, we have to eliminate 2 from LHS

y + 2 = 5

Subtracting 2 from both sides    

∵(to balance out the equation we do the operations on both side of equation)

y + 2 - 2 = 5 -2

y + 0 = 3

y = 3

2)

The given equation is

x - 18 = 20

we have to find value of x for this

adding 18 on both sides of the equation

x - 18 + 18 =20 + 18

x - 0 = 38

x = 38

3)

The given equation is

6m = 18

we have to find value of m for this

dividing 6 on both sides of the equation

                           ∴18 = 6*3

Cancelling out 6 we get

m = 3

4)

The given equation is

To find the value of h

for this multiplying 3 on both sides of the equation

it becomes

h=21

c - they will have the same distribution
