Answer:
Junior is 11 and Grandpa is 59
Step-by-step explanation:
G = 6J - 7 Get G by itself
G + J = 70
- J -J
G = -J + 70 Set the two equations equal to each other
6J - 7 = -J + 70
+J +J Add J to both sides
7J - 7 = 70
+ 7 +7 Add 7 to both sides
7J = 77 Divide both sdies by 7
J = 11

Answer:
Step-by-step explanation:
1/48 + 5/6
The LCD of 48 and 6 is 48 so we have:
1/48 + 40/48
= 41/38
Applying parallel line postulate twice
36degree=3x degree +2y degree
126 degrees=12 x degree + 2y degree
So, the two equations are:
3x + 2y = 36
and
12x + 2y = 126
Eliminate x to solve for y
-(3x + 2y)= -(36)
-3x - 2y = -36
Combine the equations
(-3x - 2y)+ (12x + 2y) = (-36) + (126)
-3x -2y + 12x + 2y = -36 + 126
9x = 90
x = 10
Plug value of x back into to the equations to solve for y
3(10) + 2y = 36
30 + 2y = 36
2y =6
y = 3
Optional
Plug x into the other equation to check for error
12(10) +2y = 126
120 + 2y =126
2y = 6
y = 3
