Answer:
x = 25
Step-by-step explanation:
120 = 70 + 2x
120 - 70 = (70 - 70) + 2x
50 = 2x
50/2 = 2x/2
x = 25

Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =  ← k is the constant of variation
 ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y =  ← is the equation of variation
 ← is the equation of variation
When y = - 9, then
- 9 =  ( multiply both sides by x )
 ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
