Divide each term by 10 to get b alone
10b = −10 = 10b/10 = -10/10
b = -1
Answer:
DE
Step-by-step explanation:
You can tell by the markings. Since there are two vertical markings it concludes that those sides are the same length.
I can’t answer if you don’t show the multiple choice...
Answer:
2x−3y=6
Step-by-step explanation:
Explanation:
Standard form: Ax + By = C
Just take 2/3x to the other side.
So the answer would be −23x+y=−2
But not yet the final answer... In standard form x can't be negative and A, B and C need to be an integers (whole numbers)
(I multiplied the whole equation by -3)
2x−3y=6
93+78 divide by 4 + 5
= 171 ÷ 9
= 19
