4th option is correct xy=-10

if this was to u plzz mark me the brainliest

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

10 times 13 = 130

10 times 13 = 130

130 + 130 = 260

if this you out can you make this answer the brainliest?
