1. y=7-3x
4x+2(7-3x)=16
4x+14-6x=16
-2x=2
x=-1
-3+y=7
y=10
(-1,10)
2. x=2y
2(2y)+2y=4
4y+2y=4
6y=4
y=2/3
x-2(2/3)=0
x-4/3=0
x=4/3

Julia has 12 years.
1/4 of that is 3 (12/4=3)
3+2 = 5
Jasmine has played for 5 years
Double Check- Reverse
5-2 = 3
3•4 = 12
We have a subtraction between two terms: h and 2g. Let's see the value of each term:
h is 4, it's already given.
2g means twice g, and g is 32. So, 2g is 64
So, the subtraction is

3x+2=14
-2 -2
3x=12
/3 /3
X=4
Always a divisor since it’s always found in the greatest common factor of all numbers
