Hey guys! I need help solving this equation! The equation is:
1 answer:
Ok so you have your two equations:
(1) 2x + 3y = -11 (I am assuming you meant 2x + 3y instead of 2x + 3x at least?)
(2) x - y = 12
x = y + 12
If we substitute equation (2) into equation (1) we get:
2(y + 12) + 3y = -11
2y + 24 + 3y = -11
5y = -35, therefor y = -7
If y = -7, from equation (2) we get:
x = -7 + 12 = 5

Answer:
The width of the rectangle is 4x^24x
2
4, x, squared
The length of the rectangle is 2x^3+3x+52x
3
+3x+5
Step-by-step explanation:
12x+1=-7
-1 -1
12x=-6
/12 /12
x=-1/2 or x=-0.5
I believe the equation is wrong
3x - 6 = 2x + 6
3x = 2x + 6 + 6
3x = 2x + 12
3x - 2x = 12
x = 12
Answer:
16
Step-by-step explanation:
3^3=27 then you have 27+13=40 now you have 56-40=16
