Question

Solve by substitution method , 3x-4y=12
And 4x-3y=24 .note - d it by substitution method and find a solution that satisfies both the equation

Answer 1

from 1

y=4x-24/3

sub y in eq 1

we get

3x-4(4x-24/3)=12

take Lcm

multiply -4with the value inside the bracket and take Lcm to whole number we get

9x-96+16x/3=12

9x-96+16x=12*3

9x-96+16x=36

9x+16x=36+96

25x=132

X=132/25

Answer 2

Step-by-step explanation:

first of all find value of x and put this value in eq 2 and then we will find the value of x and than put both the values i.e values of x and y you will see that it will satisfy both the equations
