Question

solve the following simulteneas equation by completing the activity3×-4y=7;5×+2y=3 ​

Answer 1

$\huge\mathfrak\red{YOUR ANSWER}$

3x-4y=7

first value

let the value of x be=5

let the value of y be=2

soo...

3(5)-y(2)

=> 15-8=7

second value..

let x be= -1

let y be=1

soo..

3(x)-4(y)

=> 3(-1)-4(1)

-3-4 = 7

5x+2y=3

first value..

let x be=1

let y be=-1

soo...

5(x)+2(y)

=> 5(1)+2(-1)

5+(-2)= 3

second value..

let x be= -1

let y be= 4

soo..

5(x)+2(y)

=> 5(-1)+2(4)

-5+8=3

NOW JUST PLOT THE VALUES FOUND ON GRAPH AND JOIN THE LINES OF THE TWO VALUES OF EACH POINT...

THE PLACE WHERE THE LINES WILL INTERSECT IS YOUR SOLUTION....
