Question

-3x+5=20
show work please!

Answer 1

x=−5

Explanation:

−3x+5=20

Step 1: Subtract 5 from both sides.

−3x+5−5=20−5

−3x=15

Step 2: Divide both sides by -3.

−3x/-3 = 15/-3

Answer 2

`\huge\text{Hey there!}`

`\large\text{-3x + 5 = 20}\\\large\text{SUBTRACT by 5 to BOTH SIDES}}\\\large\text{-3x + 5 - 5 = 20 - 5}\\\large\text{Cancel out: 5 - 5 because that gives you 0}\\\large\text{Keep: 20 - 5 because it gives you 15 and it helps us solve for x}\\\large\text{20 - 5 = 15}\\\large\text{New equation: -3x = 15}\\\large\text{DIVIDE by -3 to BOTH SIDES}`

`\bold{(-3)/(-3)=(15)/(-3)}\\\\\bold{Cancel\ out: (-3)/(-3)\ because\ it\ gives\ you\ 1}\\\\\bold{Keep: (15)/(-3)\ because\ it\ gives\ you\ x}`

`\bold{x = (15)/(-3)}`

`\boxed{\boxed{\bold{Answer: x = -5}}}\huge\checkmark`
