Answer:
x=8/5
Step-by-step explanation:
2/3(18x-12)=7-3(x-3)
2/3(18x-12)=7-3x+9
12x-8=-3x+16
12x-(-3x)-8=16
12x+3x-8=16
15x-8=16
15x=16+8
15x=24
x=24/15
simplify
x=8/5

Step-by-step explanation:
I divided your loan and interest rate by 5%
For direct variation:
y = kx
-12 = 9k
k = -12/9 = -4/3
Therefore, the required equation is y = -4/3 x
Answer:
x = -2 and y = 0
Explanation:
You just put the value of one variable in terms of the other in one of the two equations. Then, solve it and BOOM you'll have your solution.
x + y = -2 ........... (a)
y = x + 2 ............ (b)
Put (b) in (a),
x + (x + 2) = -2
2x = -4 => x = -2
Put x = -2 in (b),
y = x + 2 = -2+2 = 0
Thus, x=-2 and y=0
