Question

3x/5-2y/3+1=0 y/3+2x/5=4
​

Answer 1

Answer:

what to do with these equations?

Answer 2

Answer:

3x/5 - 2y/3 +1 = 0

y/3 + 2x/5 = 4

let us take X/5 as a.

and y/3 as b

3a - 2b= -1......(1)

2a + b = 4

multiply (2a + b = 4) × 2

4a + 2b = 8......(2)

add (1) and (2)

3a - 2b = -1

4a + 2b = 8

__________

7a = 7

a = 7/7

a = 1

3(1) - 2b = -1

3 - 2b = -1

-2b = -4

b = 2

.

.

a = 1

b = 2

a = X/5

1 = X/5

X= 5

b = y/3

2 = y/3

y = 6

.

.

X = 5

y = 6
