What is the answer to this equation using substitution x+y=1
1 answer:
{ x + y = 1 * ( - 2 ) 2 x + 3y = -4 - 2 x - 2 y = - 2 2 x + 3 y = - 4 _______________ y = - 6 Subsititute y = - 6 <span> 2 x + 3 y = - 4 2 x + 3 * (-6) = -4 2 x - 18 = - 4 2 x = - 4 + 18 2 x = 14 x = 14 / 2x = 7 The solution to the system of equations are: x = 7 and y = - 6 hope this helps!</span>
