Question

find the value of x of the equation 3x + y = 7 , if y = 1.​

Answer 1

Answer:

given

y=1

3x+y=7

=3x + 1 =7

= 3x = 7 - 1

= 3x = 6

= x = 6/3

= x = 2

the value of x is 2

Answer 2

Answer:

x = 2

Step-by-step explanation:

if y = 1

if y = 13x + y = 7

if y = 13x + y = 73x + 1 = 7

if y = 13x + y = 73x + 1 = 73x = 7 - 1

if y = 13x + y = 73x + 1 = 73x = 7 - 13x = 6

if y = 13x + y = 73x + 1 = 73x = 7 - 13x = 6x = 6/3

if y = 13x + y = 73x + 1 = 73x = 7 - 13x = 6x = 6/3x = 2
