Let "what" and "what" be A and B
Put this in an algebraic equation
A * B = 21
A + B = -22
A must = -21 and B must = -1 , this is because two negatives multiply to make a positive
A + B = -22 , -21 +-1 = -22
the answer in standard form is 2x -5y = -3
Possibly (1,8) I could be incorrect though
Answer:
x = 14
y = 30
Step-by-step explanation:
x + 10 = 3x - 18
x = 3x - 18 - 10
x = 3x -28
x - 3x = -28
-2x = -28
x = 14
(3x - 18) + (6y - x - 10) = 180
3x - x -18 - 10 + 6y = 180
2x - 28 + 6y = 180
2x + 6y = 180 + 28
2(14) + 6y = 208
6y = 208 - 28
6y = 180
y = 30
I hope this helps!
Answer:
-3
Step-by-step explanation:
2/5(-10x+5)+8x=3(2x+6)-10
-20/5x+10/5+8x=6x+18-10
-4x+2+8x=6x+8
-4x+8x=6x+8-2
4x=6x+6
4x-6x=6
-2x=6
x=6/-2
x=-3
