Question

Solve the equation, write the one solution, No solution and Infinitely Many Solution.

3. 20-2x = -7X​

Answer 1

x=−4

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
