X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
Answer:
The answer for y=2x−2 is x=y/2+1
Step-by-step explanation:
The <em>correct answer</em> is:
