Question

solve each system of equations by the substitution method. Tell whether each system is inconsistent or consistent. If the system is consistent, tell whether it is independent or dependent

2(x+y) -5(x+1)=3          -3x+2y=8

bahrom7893 · Answer

simplify the first equation:
$$2x+2y-5x-5=3$$$$-3x+2y=8$$simplify the first equation further:
$$2x-5x+2y-5=3$$$$-3x+2y=3+5$$$$-3x+2y=8$$

So now you have:$$-3x+2y=8$$and$$-3x+2y=8$$That's true for all x and y, so this is a consistent, dependent system.
