Y=2x/a+2b solve for a
mina [271]
Solve for a.

y=2x/a+2b

Multiply both sides by a.

ay=2ab+2x

Add -2ab to both sides.

ay+−2ab=2ab+2x+−2ab

−2ab+ay=2x

Factor out variable a.

a(−2b+y)=2x

Divide both sides by -2b+y.

a(−2b+y) / −2b+y = 2x / −2b+y

a = 2x / −2b+y

Which method is most efficient in solving a system of linear equations when two equations have x values with opposite coiffiecen
bulgar [2K]

Answer:

Elimination

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
