Simplify the second equation.
1/2y = -x + 1
Multiply both sides by 2
y = -2x + 2
Since both equations equal y you can set them equal to each other.
-2x + 2 = 3x - 1
Solve for X
-5x = -3
x = 3/5
Plug this into one of the equations.
3(3/5) - 1 = y
1.8 - 1 = y
y = .8
(0.6, 0.8)
x Margo's age
Jaun + Margo
(2x+5) + x = 29
3x = 24
x = 8, Margo's age. Jaun 21 2*8+5
And to check...
sum = 29

Answer:
See explanation
Step-by-step explanation:
First plot points A, B, C and D on the coordinate plane and connect them to get quadrilateral ABCD. Then plot the vertices E, F, G, H of the quadrilateral EFGH in each case.
For each of these cases there are attached diagrams
1 case - reflection acraoss the x-axis
2 case - translation 5 units down
3 case - reflection across the y-axis
4 case - translation 7 units right
