Question

2х - Зу = 4
5x - Зу = 7

Answer 1

Step-by-step explanation:

2x - 3y = 4

5x - 3y = 7

Simultaneous equation

Through elimination method

2x - 3y= 4

+5x -3y = 7

7x =11

Divide bith sides by 7

x = 1 4/11

substitute x for 1 4/11 in the first equation

2(11/4) - 3y = 4

22 - 3y = 4

22 - 4 = 3y

18 = 3y

Divide bith sides by 3

y = 6

Therefore,

x = 11/4

y = 6

Answer 2

So, use substitution to solve for X and Y.
X = 11/7, Y= 2/7
