Question

solve 5[4x-3{10x-2(2x+5)}]-9=1​

Answer 1

Answer:

x= −6 over 155

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(4x−310x−2(2x+5))−9=1

(5)(4x)+(5)(−310x)+(5)(−2(2x+5))+−9=1(Distribute)

20x+−1550x+−20x+−50+−9=1

(20x+−1550x+−20x)+(−50+−9)=1

(Combine Like Terms)

−1550x+−59=1

−1550x−59=1

Step 2: Add 59 to both sides.

−1550x−59+59=1+59

−1550x=60

Step 3: Divide both sides by -1550.

−1550x

−1550

= 60 over −1550

x= −6 over 155
