PLZZZZZZ HELPPPPSolve the system of equations using the substitution method. {2x+8y=4x=β3y+5 Enter your answers in the boxes.
Accepted Solution
A:
2x + 8y = 4 x = -3y + 5
plug in the value of x, from the second equation, into the first 2(-3y + 5) + 8y = 4 -6y + 10 + 8y = 4 combine like terms 2y + 10 = 4 subtract 10 2y = -6 divide both sides by 2 y = -3
then, plug what you got for y into one of the equations x = -3y + 5 x = -3(-3) + 5 x = 9 + 5 x = 14
