X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer: X=13/3
Step-by-step explanation:
1. Multiply Both sides by 12
8x-10=5x+3
2. Collect the like terms, calculate the sum
8x-5x=3+10
3.Divide both sides by 3
3x=13
Answer X=13/3
Alternative Form,
X= 4 1/3, X=4.3
