Question

What should be added to -3a + 7b -16 to get 4a - 3b + 19?

Answer 1

Answer:

= 7a + 10b + 35

Step-by-step explanation:

solution,

 (-3a + 7b - 16) + x = 4a - 3b + 19

or,  -3a + 7b - 16 + x = 4a - 3b + 19

or, x = 4a +3a - 3b - 7b + 19+ 16

∴ x = 7a + 10b + 35

Answer 2

Answer:

___________

1st equation = -3a + 7b - 16

let , other number be = x

sum of two numbers = 4a - 3b + 19

$\mathfrak\red{\underline{Solution}}$

-3a + 7b - 16 + x = 4a - 3b + 19

x = 4a - 3b + 19 + 3a - 7b + 16

x = 7a - 10b + 35

° Hence , ( 7a - 10b + 35 ) should be added to ( -3a + 7b - 16 ) to get ( 4a - 3b + 19 ) .
