5x+4y=3

x=2y-15

solve for y and x

x=9, y=12

Step-by-step explanation:

-5x+4y=3 A

x=2y-15B

Putting the value of x from B in A

-5(2y-15) +4y=3

-10y+75+4y=3

-6y=3-72

-6y=-72

y=72/6= 12

Putting the value of y =12 in B

x= 2(12)-15

x= 24-15

x=9

d. 9

step-by-step explanation:

54/12 = 4.5

sf = 4.5

so x = 2 · 4.5 = 9

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
