Given that 4x - 5y = 12 find y when x= -3

4x -5y = 12. 5y =4x -12. y = (4/5) x -12/5

Step-by-step explanation:

Explanation:

4x - 5y = 12

x = -3

4(-3) - 5y = 12

-4 · 3 - 5y = 12

-12 - 5y = 12

-12 - 5y + 12 = 12 + 2

-5y = 24

-5y / -5 = 24 / -5

y = ⁻²⁴⁄₅

y = -4.8

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
