Question

7a - 3b = 38
2a + 5b = 37

Answer 1

a ) 7a - 3b = 38

solve for a : 7a = 38 + 3b

7a = 3b + 38

7a / 7 = 3b + 38 / 7

a = 3b + 38 / 7

solve for b : - 3b = 38 - 7a

- 3b / - 3 = 38 - 7a / - 3

b = 38 - 7a / - 3

b = 7a - 38 / 3

b ) 2a + 5b = 7

solve for a : 2a = 37 - 5b

2a / 2 = 37 - 5b / 2

a = 37 - 5b / 2

solve for b : 5b = 37 - 2a

5b / 5 = 37 - 2a / 5

b = 37 - 2a / 5

hope helpful for you

Answer 2

Answer:

a=301/41

b=183/41

Step-by-step explanation:

first 3*5=15

lets multiply the both side of first equation with 5

then multiply the second equation with 3

then u can easily vanish the "b" and can get the value of "a".. and that's how u can also get the value of "b"
