x = 0
y = 2/3
Step-by-step explanation:
Step: Solve x + 6y= 4 for x:
x + 6y + −6y = 4 + −6y
x= −6y + 4
Step: Substitute −6y + 4 for x in 2x + 3y = 2:
2x + 3y = 2
2 (−6y + 4) + 3y = 2
−9y + 8 = 2
−9y + 8 + −8 = 2 + −8
−9y = −6
-9y/-9 = -6/-9
y = 2/3
Step: Substitute 2/3 for y in x = −6y + 4:
x = −6y + 4
x = -6 (2/3) + 4
x = 0
Sorry if it is long and confusing. But I hope this helps!
