Hi there!
Th' Eqn. is :-
4 (x - 3) = 2 (3x + 1)
=> 4x - 12 = 2 (3x + 1)
=> 4x - 12 = 6x + 2
Combine th' like terms :-
=> 4x - 6x = 2 + 12
=> - 2x = 14
=> x =

=> x = - 7
Hence, The required answer is : x = - 7
~ Hope it helps!
Answer: 56 degrees
Step by step:
The three angles in a triangle add up to 180 degrees.
49 + 75 + the third angle = 180
Let’s simplify.
180 - 49 - 75 = the third angle
So, by subtracting, we know that the third angle is 56 degrees!
Hope this helps! Please tell me if I did anything wrong, thank you so much and have a good day!
80% of x = 0.80x or 4x/5
Any fraction equivalent to 80/100 can be used to multiply x. You could also divide x by any equivalent to 5/4 or 1.25.
Your answer is 67.5. Hope this helps!
