The solution to the given system of equation is (25/7, 6/7)
<h3>System of equation</h3>
Given the system of equation expressed as:
x= - 4y+7 ........... 1
-2y+3x=9 ...........2
Substitute the equation 1 into 2 into have:
-2y + 3(-4y+7) = 9
-2y + 3(-4y) + 3(7) = 9
-2y - 12y + 21 = 9
Collect the like terms
-14y = 9- 21
-14y = -12
y = 6/7
Substitute y = 6/7 into equation 1;
x =-4y + 7
x = -4(6/7) + 7
x= -24/7 + 7
x = -24+49/7
x = 25/7
Hence the solution to the given system of equation is (25/7, 6/7)

ANSWER: ABC and probably e but not sure about that one
EXPLANATION:
A proportional relationship is a relation between two quantities in which the ratio of one quantity to the other quantity is constant… hope this was helpful ;)
Answer:
x = -1.5
Step-by-step explanation:
(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
*I would first change any minus signs that are outside of the parenthesis to a plus sign. This is optional, not necessary. *
0.5x + 1.2 + (-3.6) + 4.5x = 4.8–0.3x + 10.5x + 0.6
*Now combine like terms on each side. *
5x + (-2.4) = 10.2x + 5.4
*move all Xs on one side.*
-5.2x = 7.8
*Divide both sides by -5.2 to get X by itself."
x = -1.5
For my calculations the answer is 5
