In this item, we are given with a system of linear equation as written below.
y = 0.5x + 3.5
y = -2x/3 + 1/3
To determine the values of x and y, we use the substitution method. We substitute the expression for y from the first equation to that of the second equation so that the equation becomes.
0.5x + 3.5 = -2x/3 + 1/3
Multiply the equation by 6.
3x + 21 = -4x + 2
Transpose all the terms with variables to one side and the constants to the other.
(3x + 4x) = 2 - 21
7x = -19
Divide the equation by 7,
x = -19/7
The value of y,
y = (0.5)(-19/7) + 3.5 = 15/7
<em>ANSWER:</em>
<em> x = -19/7</em>
<em> y = 15/7</em>
Answer:
If he has 2000 dollars to spend in total, that will go on one side of the inequality. Everything he spends goes on the other. 2000 is the maximum he can spend. He is going to sped 637 on an airline ticket plus x on other expenses.
2000>= 637+ x
Subtract 637 from each side
2000-637 >= 637-637 +x
1363>= x
