Question 22233: 6(X+9)+9=-7{9X+5)+7x
SOLUTION
TO GET THE VALUE OF X =
6(X+9)+9= -7(9X+5}+ 7X
6X+54+9 = -63x-35+7X BY MULTIPLYING THE BRACKET OUT
6X+63X-7X = -35-54-9 BY COLLECTING THE LIKE TERMS BY ISOLATING THE UNKNOWN
62X = -98
X= -98/62
X= -1.58
WE CAN ALSO CHECK IF WE ARE RIGHT BY SUBTITUTING -1.58 IN THE EQUATION,IF WE DO SO THE LEFT HAND SIDE MUST EQUAL TO THE RIGHT HAND SIDE.
Let's see.
6x+54+9= -63x-35+7x
6(-1.58)+54+9 = -63(-1.58)-35+7(-1.58)
-9.48+54+9 = 99.54-35-11.06
53.52 = 53.48
54=54
SO OUR VALUE OF X is correct.
