Solve the equation, write the one solution, No solution and Infinitely Many Solution. 3. 20-2x = -7X​

x=−4

Step-by-step explanation:

Rearrange terms

20−2=−7

−2+20=−7

Subtract 20 from both sides of the equation

−2+20=−7

−2+20−20=−7−20

Subtract the numbers

−2=−7−20

Add 7 to both sides of the equation

−2=−7−20

−2+7=−7−20+7

Simplify

5=−20

Divide both sides of the equation by the same term

5x=-20

5x/5=-20/5

Simplify

x=-4

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
