Answer: Add 5 to both sides

What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?

Answer- Add 5 to both sides

(4/7)x - 5 = -13

• As mentioned above, first step would be,

adding 5 to both sides

=> (4/7)x - 5 + 5 = -13 + 5

=> (4/7)x = -8

• Now, transporting 7 from L.H.S. to R.H.S

=> 4x = -8 × 7

=> 4x = -56

• Now in the same way, transporting 4 from L.H.S. to R.H.S

=> x = (-56/4)

=> x = -14

• And in this way, or taking<u> (Add 5 to both sides)</u> as our first step, we find that the value of x is -14.

<u>∴ </u><u> </u><u>x = -14</u>

Hope it helps.

Solve for e.<br> 0.75(8 + e) = 2 - 1.25e
timofeeve [1]

Answer:

e = -2

Step-by-step explanation:

Well to solve for e in the following equation,

.75(8 + e) = 2 - 1.25e

We need to distribute and use the communicative property to find <em>e</em>.

6 + .75e = 2 - 1.25e

-2 to both sides

4 + .75e = -1.25e

-.75 to both sides

4 = -2e

-2 to both sides

e = -2

<em>Thus,</em>

<em>e is -2.</em>

<em />

<em>Hope this helps :)</em>
