5[3(x+4)-2(1-x)]-x-15=14x+55 what is x
1 answer:
Answer:
The value of x is 2
Step-by-step explanation:
Given expression as :
5 [ 3 (x + 4) - 2 (1 - x) ] - x - 15 = 14 x + 55
Or , 5 [ 3 x + 12 - 2 + 2 x ] - x - 15 = 14 x + 55
Or, 5 [ 5 x + 10 ] - x - 15 = 14 x + 55
Or, 25 x + 50 - x - 15 = 14 x + 55
Or , 24 x + 35 = 14 x + 55
Or, 24 x - 14 x = 55 - 35
Or, 10 x = 20
∴ x = = 2
Hence The value of x is 2 . Answer

Answer: x=0
Step-by-step explanation:
Multiply both sides of the equation by 35, the least common multiple of 5,7.
7×4x−5×3x=5×4x+5×5x
Multiply 7 and 4 to get 28.
28x−5×3x=5×4x+5×5x
Multiply −5 and 3 to get −15.
28x−15x=5×4x+5×5x
Combine 28x and −15x to get 13x.
13x=20x+25x
Combine 20x and 25x to get 45x.
13x=45x
Subtract 45x from both sides
13x−45x=0
Combine 13x and −45x to get −32x
−32x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −32 is not equal to 0, x must be equal to 0.
X=0
