2x+8y=20 y=2 using substitution method

Answer 1

there is an app called photomath which allows you to take a picture of the problem and gives you a step by step answer

Answer 2

Substitute y = 2 in 2x + 8y = 20 to get

2x + 8y = 20
>> 2x + 8(2) = 20
>> 2x + 16 = 20
>> 2x + 16 -16 = 20 - 16
>> 2x = 4
>> 2x / 2 = 4 / 2
>> x = 2

So x = 2, y = 2 is the solution. In order pair form (x,y) = (2,2)
