multiply by -2:
-2/-2 *y = -5*-2
y = 10
Multiply by 4/3:
4/4*3/3*h = -12*4/3
h = -16
Add 4 to both sides:
17+4 = 3t -4+4
21 = 3t
Divide both sides by 3:
21/3 = 3/3*t
7=t

y/-2 = -5, y = 10
3/4h = -12, h = -16
17 = 3t -4, t = 7

if 10/2=5 so that 10/-2=--5, so y =10, you must think it your self. it have another way , y/-2= -5, so that -2 x --5 will guve back to y. or you can think that 10. for other , 3/4h=-12. h = -1/16. t=7.

y/-2=-5
-2(y/-2)=-5(-2)
y=10
3/4h=-12
3/4h(4/3)=-12(4/3)
h=-48/3
h=-16
17=3t-4
21=3t
7=t
