Question

The sum of two numbers is 70 and their difference is 6. Vid the
cross-multiplication method.​

Answer 1

Step-by-step explanation:

Let x and y are two number such that

x + y = 70 and x - y = 6

here we have two linear equations in two variables : x + y = 70 and x - y = 6

we have to solve cross multiplication method,

1.x + 1.y - 70 = 0

1.x + (-1).y - 6 = 0

now, \bf{\frac{x}{1.(-6)-(-1).(-70)}=\frac{-y}{1.(-6)-1(-70)}=\frac{1}{1.(-1)-1.1}}

1.(−6)−(−1).(−70)

x

=

1.(−6)−1(−70)

−y

=

1.(−1)−1.1

1

\bf{\frac{x}{-76}=\frac{-y}{64}=\frac{1}{-2}}

−76

x

=

64

−y

=

−2

1

x/-76 = 1/-2 => x = 76/2 = 38

hence, x = 38

similarly, -y/64 = /1-2 => y =64/2 = 32

hence, y = 32

therefore, two numbers are 38 and 32
