4x-1 + 2x-1 = 5x how do i solve this problem?

2=x

Step-by-step explanation:

4x-1 + 2x-1 = 5x

First combine like terms together

4x-1 + 2x-1 is 4x+2x-1-1

4x+2x-1-1 =6x-2

4x-1 + 2x-1=6x-2

6x-2=5x

The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced

6x-6x-2=5x-6x

0-2=-1x

-2=-1x

Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide

-2/-1=-1x=-1

2=x

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
