Consider the system of linear equations. 7 x + 16 y = negative 2. 9 x minus 4 y = 22. to use the linear combination method and addition to eliminate the y-terms, by which number should the second equation be multiplied? –4 negative one-fourth one-fourth 4

your answer would be 12

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

its very big question plz make it small
