Question

write the value of y in x=-1 if x=-1​

Answer 1

Step-by-step explain

Given, 4x + 5y = 19

Given, 4x + 5y = 19x = 1

Given, 4x + 5y = 19x = 1 substituting,

Given, 4x + 5y = 19x = 1 substituting,4 (1) + 5y = 19

Given, 4x + 5y = 19x = 1 substituting,4 (1) + 5y = 19= 5y = 19 - 4

Given, 4x + 5y = 19x = 1 substituting,4 (1) + 5y = 19= 5y = 19 - 4= 5y = 15

Given, 4x + 5y = 19x = 1 substituting,4 (1) + 5y = 19= 5y = 19 - 4= 5y = 15∴y=3
