Let's solve this using unitary method ~
Therefore , the ostrich will run 105 meters in 5 seconds.
Answer:
x = 
Step-by-step explanation:
Given equation is,
ax + 3 = 23
To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.
Step 1,
Subtract 3 from both the sides of the equation.
ax + 3 - 3 = 23 - 3
ax = 20
Step 2,
Divide the equation by a,

x = 
Therefore, x =
will be the answer.
The numbers are 32 and 21
32 + 21 = 53
32 - 21 = 11
