100 points and brainiest if correct: What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?

Subtract 13 from both sides
Divide both sides by 7
Add 5 to both sides
Multiply both sides by 4

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 (Add 5 to both sides) as our first step, we find that the value of x is -14.

∴ x = -14

Hope it helps.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
