Q:
4X-5y=136x +2y =48Elimination
Accepted Solution
A:
Answer:The answer to your question is: (7, 3)Step-by-step explanation:Equations 4x - 5y = 13 (I) 1.- Assign numbers to each equation 6x + 2y = 48 (II)2.- Multiply (I) by 3 and (II) by -2 12x - 15y = 39 (I)' -12x - 4y = -96 (II)'3.- Sum the equations 0 - 19y = -57 4.- Find y y = -57/-19 y = 35.- Find x 4x - 5(3) = 13 Substitution 4x - 15 = 13 Simplifying 4x = 13 + 15 4x = 28 x = 28/4 x = 7Result (7, 3)
