L = liz's age now
J = Jack's age now
L-1 and J-1 are their ages one year ago
L-1=3(J-1)
L-1=3J-3
L=3J-3+1
L=3J-2 (to be used later)
L+2 and J+2 are their ages in two years
L+2=2(J+2)
replace L by 3J-2
3J-2+2=2(J+2)
3J=2J+4
3J-2J=4
J=4 is Jack's age now
L-1=3(J-1)
L-1=3(4-1)
L-1=3*3
L-1=9
L=9+1
L=10 is Liz's age now
Answer:
3 1/3, or 10/3
Step-by-step explanation:

Answer:
The equation of this line would be y = -1/2x + 1
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we need to solve the original equation for y.
2x + 4y = 16
4y = -2x + 16
y = -1/2x + 4
The original slope (the coefficient of x) is -1/2, which means the new slope will also be -1/2 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 2 = -1/2(x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1
