A Brief well explained step by step process of how to solve this problem using the substitution method ------> X=y+8 and 4x+2y=2

Question

------> X=y+8 and 4x+2y=2 what is the best step by step well explained process using the substitution method.

Answer 1

x= y+8

4x +2y =2 divide by 2

2x +y = 1, replace x with y+8

2(y+8) +y =1

2y +16 +y = 1, combine like terms

3y = -15, divide by 3

y = -5

x = -5+8 = 3
