Answer:

-4.25

Step-by-step explanation:

When x = -1, the equation is 5(-1) - 8y = 29. This simplifies to -5 - 8y = 29. Add 5 to both sides to get -8y = 34. Divide -8 from both sides to get y = -4.25.

Hope it helps!

Tell which equation you would choose to solve for one of the variables when solving the system by substitution. 2x+3y=5 4x-y=3

PtichkaEL [24]

i would solve 4x-y =3 for y because the coefficient for y is 1

subtract 4x from each side

-y = -4x+3

divide by -1

y = 4x-3
