One number is x
other number is 3x-10

x + 3x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15 ← one number

the other number = 3x - 10 = 3*15 - 10 = 35

Solve 3(x - 4) = 11x

Ivanshal [37]

Answer:

$x = \frac{-3}{2}$

Step-by-step explanation:

3(x - 4) = 11x

Expand the brackets:

3x - 12 = 11x

Subtract 3x from both sides to isolate the -12:

3x - 12 = 11x

3x - 3x - 12 = 11x - 3x

-12 = 8x

8x = -12

Divide both sides by 8:

$\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\$

Simplify fraction:

$x = \frac{-12}{8}$

$x = \frac{-12 \div 4}{8 \div 4}\\x = \frac{-3}{2}$

Hope this helps!
