Answer:
Step-by-step explanation:
The equation Thomas wrote is:
...equation 1
Let us subtract 3x from both sides to get:
We now multiply through by 2 to get:
....equation 2
We can see that equation one and two are equivalent and hence have the same solution.
Therefore Sandra's equation is 
X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
Answer:
the answer is 83/13 and its simplification is shown in the picture. 6(5/13)
Answer:
x =
/13 ≈ 0.48
Step-by-step explanation:
13x² = 3
x² = 3/13
rationalize the denominator
x =
/13
