5x- 3/2x= -4 -7/2
10/2 x - 3/2x= -8/2 -7/2
7/2x= -15/2
7x= -15
x= -15/7
Answer:
A
Step-by-step explanation:
Given the 2 equations
6x + 3y = 9 → (1)
2x + 3y = 1 → (2)
Subtracting the 2 equations term by term eliminates the y- term
Subtract (2) from (1) term by term, that is
(6x - 2x) + (3y - 3y) = 9 - 1
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
2(2) + 3y = 1
4 + 3y = 1 ( subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
The solution is x = 2, y = - 1 → A

<u><em>Answer:</em></u>
<u><em>Your correct answer is x = 42
.</em></u>
<u><em>My Step-by-step explanation:</em></u>
<u><em>Just turn the problem around by changing the subtraction to addition: 100 – x = 58 means the same thing as 100 – 58 = x, so x = 42.</em></u>
