solve the following
0.3(x - 4) = 0.03(4x - 8)
ANSWER:
0.3(x - 4) = 0.03(4x - 8)
Remove the brackets by multiplying term by term.
==> 0.3(x - 4) = 0.03(4x - 8)
==> 0.3 * x - 0.3 * 4 = 0.03 * 4x - 0.03 * 8
==> 0.3x - 1.2 = 0.12x - 0.24
collect like terms together,(That is x terms and constant terms seperately)
For that,
0.3x - 1.2 = 0.12x - 0.24
add 1.2 on both sides. (FOR COLLECTING CONSTANT TERMS)
==> 0.3x - 1.2 + 1.2 = 0.12x - 0.24 + 1.2
==> 0.3x = 0.12x + 9.6
Subtract 0.12x from both sides. (FOR COLLECTING X TERMS TOGETHER)
==> 0.3x -0.12x = 0.12x + 9.6 - 0.12x
==> 0.18 x = 9.6
Divide both sides by 0.18
==> 0.18 x / 0.18= 9.6/0.18
==> X = 5.333333
SO, x = 5.33
