Answer:
Answer:
x = 7
y = 1
Step-by-step explanation:
3x - 4y = 17
x - 4y = 3
Solve x in the second equation.
x = 3 + 4y
Put x as 3 + 4y in the first equation and solve for y.
3(3 + 4y) - 4y = 17
9 + 12y - 4y = 17
9 + 8y = 17
8y = 17 - 9
8y = 8
y = 8/8
y = 1
Put y as 1 in the second equation and solve for x.
x = 3 + 4(1)
x = 3 + 4
x = 7
