Answer:
x=16 because when they both cross the equal to sign their operational sign changes thus u subtract n make x the subject
Answer:
x = - 16
Step-by-step explanation:
The equation relating two proportional quantities is
y = kx ← k is the constant of proportionality
To find k use the condition when y = 1, x = - 4
k =
= - 
y = -
x ← equation of proportionality
when y = 4, then
4 = -
x (multiply both sides by - 4 )
x = - 16

ZX: 17
VX: 34. I have a pic attached but it probably doesn’t make much sense :)
