Please help I’m kinda new at this kinda math

2/3

Step-by-step explanation:

Subtract 1/6 from both sides to get d by itself. After this subtraction, you should be left with 4/6 = d. Simplify the fraction to get 2/3.

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 .
