Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
Let's first draw a diagram visually representing the problem so that we can better understand it. The diagram is attached above.
Next we will establish the following:
Perimeter of a triangle = The sum of the length of all three sides of the triangle
75 = ( 4x - 3 ) + ( 4x - 3 ) + ( x )
75 = 9x - 6
9x - 6 = 75
9x = 75 + 6
9x = 81
x = 81 / 9
x = 9
FINAL ANSWER:
Therefore, the answer is:
x = 9
Hope this helps! :)
Have a lovely day! <3
