4w+3y=2

Subtract 3y from both sides of the equation.

4w=2-3y

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

w,1,y

Since w,1,y contain both numbers and variables, there are two steps to find the LCM. Find LCM for the numeric part 1,1,1 then find LCM for the variable part w1,y1.

The LCM is the smallest positive number that all of the numbers divide into evenly.

1. List the prime factors of each number.

2. Multiply each factor the greatest number of times it occurs in either number.

The number 1 is not a prime number because it only has one positive factor, which is itself.

Not prime

The LCM of 1,1,1 is the result of multiplying all prime factors the greatest number of times they occur in either number.

1

The factor for w1 is w itself.

w1=w

w occurs 1 time.

The factor for y1 is y itself.

y1=y

y occurs 1 time.

The LCM of w1,y1 is the result of multiplying all prime factors the greatest number of times they occur in either term.

w⋅y

Multiply w by y.

wy

wy

Multiply each term in 4w=2-3y by wy in order to remove all the denominators from the equation.

4w⋅(wy)=2⋅(wy)-3y⋅(wy)

Cancel the common factor of w.

Factor w out of wy.

4w⋅(w(y))=2⋅(wy)-3y⋅(wy)

Cancel the common factor.

4w⋅(wy)=2⋅(wy)-3y⋅(wy)

Rewrite the expression.

4⋅y=2⋅(wy)-3y⋅(wy)

4y=2⋅(wy)-3y⋅(wy)

Cancel the common factor of y.

Move the leading negative in -3y into the numerator.

4y=2wy+-3y⋅(wy)

Factor y out of wy.

4y=2wy+-3y⋅(yw)

Cancel the common factor.

4y=2wy+-3y⋅(yw)

Rewrite the expression.

4y=2wy-3⋅w

4y=2wy-3w

4y=2wy-3w

Rewrite the equation as 2wy-3w=4y.

2wy-3w=4y

Factor w out of 2wy-3w.

Factor w out of 2wy.

w(2y)-3w=4y

Factor w out of -3w.

w(2y)+w⋅-3=4y

Factor w out of w(2y)+w⋅-3.

w(2y-3)=4y

w(2y-3)=4y

Divide each term by 2y-3 and simplify.

Divide each term in w(2y-3)=4y by 2y-3.

w(2y-3)2y-3=4y2y-3

Cancel the common factor of 2y-3.

Cancel the common factor.

w(2y-3)2y-3=4y2y-3

Divide w by 1.

w=4y2y-3

w=4y2y-3

w=4y2y-3

w=4y2y-3

Solve for w 4/w+3/y=2
