3x+bx=a
x(3+b)=a
x=a/(3+b)

you want to get the x on the same side of the equal sign
sooo...
3x+bx=a
factor out an X
x(3+b)=a
multiply buy 1/(3+b)
x= a/(3+b)

If you have 3x=a-bx, you can add bx to both sides.
Now, by the addition property of equality, you have bx+3x=a.
bx+3x is equal to x(b+3) by the distributive property, so x(b+3)=a.
Now divide both sides of the equation by (b+3), and you have x=a/(b+3)

3x + bx = a
(3 + b) x = a
x = a / (3 + b)

3x=a-bx
3x+bx=a
x(3+b)=a
x=a/(3+b)
x=a/(b+3) which is your answer
you have to do the same thing to both sides of the equations to get your answer

Add bx to both sides.
3x+bx=a
Factor x
x(b+3)=a
x=a/(b+3)

3x=a-bx
3x + bx = a
(3+b)x = a
x = a/(3+b) QED

because of the fact x/3 is composed of the variable to remedy for, pass it to the left-hand ingredient of the equation by making use of subtracting from the two factors. to function fractions, the denominators could desire to be equivalent. The denominators may be made equivalent by making use of looking the least worry-loose denominator (liquid crystal demonstrate). consequently, the liquid crystal demonstrate is 6. next, multiply each fraction by making use of component to a million which will create the liquid crystal demonstrate in all the fractions. finished the multiplication to offer a denominator of 6 in each expression. combine the numerators of all expressions that have worry-loose denominators. combine all like words interior the numerator. because of the fact -7 would not incorporate the variable to remedy for, pass it to the wonderful-hand ingredient of the equation by making use of including 7 to the two factors. upload 3 to 7 to get 10. Multiply each term interior the equation by making use of 6. Simplify the left-hand ingredient of the equation by making use of canceling the worry-loose words. Multiply 10 by making use of 6 to get 60. i defined to you
