Question

5. Find the values of a, b, c, d from the equation
​

Answer 1

By comparing ....

a-b = 1

2a + c = 5

2a-b = 0

3c + d = 2

=> a = 1+b ----- (1)

=> 2( 1+b) - b = 0

=> 2 + 2b - b = 0

=> 2 + b = 0

=>{ b = -2 }

Now

a = 1+b

=> a = 1+ (-2)

=> {a = -1}

also

2a + c = 5

=> 2 (-1) + c = 5

=> -2 + c = 5

=>{ c = 7 }

meanwhile ;

3c + d =2

=> 3 (7) + d = 2

=> 21 +d = 2

=>{ d = -19}

Here's your answer
