Question

4x-5y=17,3x+4y=5 by elimination form, solve for x and y

Answer 1

Answer:

x = 3 , y = -1

Step-by-step explanation:

Let a1x + b1 y = c1

a2x + b2y = c2

take LCM for a1 , a2

Now make a1 = a2

Further subtract equation 1 from 2 , such that x gets eliminated

Now it is linear equation in 1 variable

Solve find y , substitute in any one equation , find x
