To solve, we must get x by itself. the first step we must take is to remove all of the parentheses. To do this, we must use distribution to multiply 5 by x - 6.
5(x - 6) = 3x - 18 + 2x
5x - 30 = 3x - 18 + 2x
Next, we must add like terms.
5x - 30 = 5x - 18
Finally, we must get x by itself. to do this, we must subtract 5x from both sides.
5x - 30 - 5x = 5x - 18 - 5x
Then, we add like terms again.
-30 = -18
Because this is a false statement, the equation is a contradiction.
The answer is 7 because when you divide 50 from 350 I️t gives you seven.
Hope this helped!!!!!!!!!!!!
The solution is -5/4= -1 1/4
44 chicken and 28 rabbits
Given:
chicken head + rabbit head = 72 heads
chicken feet + rabbit feet = 200 feet
c + r = 72
2c + 4r = 200
find the value of c using the 1st equation:
c = 72 - r
substitute c by its value in the 2nd equation:
2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28
c = 72 - r
c = 72 - 28
c = 44
c = 44 ; r = 28
To check:
2c + 4r = 200
2(44) + 4(28) = 200
88 + 112 = 200
200 = 200
