They are both equal to y so you can set them equal to each other to solve for x:
14x - 6 = -4x + 48
18x = 54
x = 3
To solve for y just plug 3 into the x of one of the given equations
y = 14(3) - 6
y = 42 - 6
y = 36
To check:
36 = 14(3) - 6
36 = 42 - 6
36 = 36
36 = -4(3) + 48
36 = -12 + 48
36 = 36
Hope this helped!
Answer:
2.25 hours
Step-by-step explanation:
Given data
distance= 36 km
speed= 16 km/h
Speed= distance/time
substitute
16= 36/t
t= 36/16
t= 2.25 hours

One way to check if 102 ÷ 6 = 17 is by focusing on the left side of the equation.
102 ÷ 6 can be converted into
can be simplified, lets start by dividing the numerator and denominator by 2.
\frac{102/2}{6/2} = \frac{51}{3}
=
can be rewritten as 17.
