3x+2(4x-4)=3 - remove parentheses
3x+ 8x-8=3 - collect like terms
11x- 8 =3 - move the constant to the right
11x=3+8 - calculate
11x = 11 - divide both sides by 11
x= 1

The sum of two numbers is 18. The quotient of the two numbers is 17. What are the two numbers?
posledela
Let the two numbers be x and y
x + y = 18 . . . . . . . . (1)
x/y = 17 . . . . . . . . (2)
from (2): x = 17y
substituting for x in (1), gives
17y + y = 18
18y = 18
y = 18/18 = 1
x = 17y = 17(1) = 17

Therefore the two numbers are: 1 and 17

Solve for x: 3/2 + 1/2x =2x​
storchak [24]

\huge{ \boxed{ \bf{ \red{Problem:-}}}}

<h3>Solve for x: 3/2 + 1/2x =2x</h3>

\huge{ \boxed{ \bf{ \red{Solution:-}}}}

\bold{ \frac{3}{2}  +  {\frac{1}{2} x = 2x}}

\bold{ ⇒\frac{3}{2}  + {\frac{x}{2}  = 2x}}

\bold{⇒\frac{3 + x}{2}  = 2x}

\bold{⇒3 + x = 2(2x)}

\bold{⇒3 + x = 4x}

\bold{⇒3 = 4x - x}

\bold{⇒ \frac{3}{3}  = x}

\bold{ \therefore{x = 1}}

<h3>Hope it's helpful</h3>
