-8x/5+1/6=-5x/3 I don't get how to find the answer?

Answers

In order to find this answer we have to manipulate the equation algebraically so that we end up with a statement that x = something. We can manipulate the problem however we need to as long as we do the same thing to both sides of the equation (this keeps the equation true).

-8x/5 + 1/6 = -5x/3

first lets get the x's on one side of the equals sign by adding 8x/5 to each side.

1/6 = -5x/3 + 8x/5

Ok, now let's add the x's together (we need common denominators)

1/6 = -25x/15 + 24x/15
1/6 = -x/15

Now lets get x by itself by multiplying each side by 15

1/6 * 15 = -x
15/6 = -x
3/2 = -x

Multiply each side by -1 to make the x positive.

-3/2 = x

How do you solve the equation 0.4(2x+0.5)=3[0.2x+(-2)]-4

Answers

0.4(2x+0.5)=3[0.2x+(-2)]-4

0.8x+0.2=0.6x-6-4

0.8x-0.6x=-6-4-0.2

0.2x=-10.2

x=-10.2/0.2

x=-51

$0.4(2x+0.5)=3[0.2x+(-2)]-4$

$0.8x+0.2=0.6x-10$

$0.2x=-10.2$

$x= (-10.2)/(0.2)$

$x=-51$
