Question

Write a real word problem that cold be solved by using the equation 3x- 25= 125

Answer 1

Two teams are playing basketball. Team 1 scored 3.5 times the number of points per basket. Team 2 scored 8 times the number of points per basket. They would've each scored the same amount of points if Team 1 had scored 54 more points.
Solve:
54+3.5x=8x :Write out the equation
-3.5x -3.5x :Subtract 3.5x from both sides to isolate the variable
54=4.5x :Simplify
/4.5 /4.5 :Divide by 4.5 on both sides
12=x :Answer=12
Next you would find each team's score:
8x= 8(12)= 96 :substitute and solve
Each team score is 96 points
(Note: Since each team score was equal, you don't have to solve for each team, just one and preferably the easier one, and that is the score that each team scored.)

Answer 2

Answer:

If we have a problem,

In a school there are 125 girls which is 25 less than 3 times of the number of boys how many boys are there ?

Let x be the number of boys,

So, the number of girls = 3 × number of boys - 25

= 3x - 25,

∵ Number of girls = 125

⇒ 3x - 25 = 125

Hence, the above real word problem could be solved by the given equation.
