Step-by-step explanation:
Given pair of equations is 8x+5y=9 and 3x+2y=4
To find out: Solution of the given equations using the cross multiplication method.
The equations can be written as:
8x+5y−9=0
3x+2y−4=0
By cross multiplication method, we know that, for a system of linear equations in x and y, of the form a1x+b1y+c1=0 and a2x+b2y+c2=0, we have:
b1c2−b2c1x=c1a2−c2a1y=a1b2−a2b11
∴ 4(−5)−2(−9)x=(−9)(3)−(−4)(8)y=
