Answer:
So lets isolate y
we have
-2x+3y=9
2/3x +2y=0
Im gonna do the first equation
so -2x + 3y = 9
Add 2x on both sides
3y= 9+ 2x
Now divide by 3 to isolate y
y= 3+ 2/3x
Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.
2/3x+ 2(3+ 2/3x)= 0
Solve:
2/3x+ 6 + 4/3x = 0
6/3x +6= 0
2x+6=0
2x= -4
x= -2
Now we can subsitute this for any equation.
so I’m gonna do the first equation
-2(-2)+3y=9
4+3y=9
3y= 5
y= 5/3
y= 1 2/3
Final answer:
x=-2
y= 1 2/3
-0.07(q- -6) + -4.67 = -5.3
Distribute the -0.07
-0.07q + -0.42 + -4.67 = -5.3
Combine like terms
-0.42 + -4.67= -5.09
-0.07 - 5.09= -5.3
Add 5.09 to both sides
-0.07q= -0.21
Divide both sides by -0.07
Q= 3
