Question

4 x minus 3 Y equal 8 x - 2y = - 3 substitution method​

Answer 1

Answer:

Step-by-step explanation:

4x - 3y = 8

4x = 8 + 3y

x = 8 + 3y/4

substitute this in x - 2y = -3

8 + 3y/4 - 2y = -3

On L.C.M,

8 + 3y -8y/4 = -3

3y - 8y + 8 = -12

3y - 8y = -12 -8

-5y = -20

therefore, y = 4

it is given that x = 8 + 3y/4

x = 8 + 3(4)/4

x = 8 + 12/4

x = 20/4

therefore, x is 5

so y is 4 and x is 5
