Answer:
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
