-5x+4y=7 y=-2x-8

x = 13, y = 18

hope this is right

x=−3 and y=−2

Step-by-step explanation:

-5x+4(-2x-8)=7

-13x-32=7

-13x-32+32=7+32

-13x=39

divide both sides by -13

x=-3

substitute x for -3

-2(-3)-8= -2

y= -2

part a: 1.08

part b: 27.59

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
