x + y = 12
Equation 2: Difference:
x - y = 4
Solution:
x + y = 12
x - y = 4
-------------
Add the two equations together:
2x = 16
Divide both sides by 2:
x = 8
Solve for y:
Use equation 1 substituting for x:
x + y = 12
8 + y = 12
Subtract 8 from both sides:
y = 4
Answer:
one number is 8 and the other number is 4.
8 + 4 = 12
8 - 4 = 4

Answer:
The answer is
<h2>4260 N</h2>
Step-by-step explanation:
The force acting on an object when given the mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 142 kg
acceleration = 30 m/s²
So we have
Force = 142 × 30
We have the final answer as
<h3>4260 N</h3>
