2x+3=-x+6
3x=3
x=1
y=2(1)+3
y=2+3
y=5
hope this helps :D
The answer to your question is
(7)-9= -54
Answer:
Below in bold.
Step-by-step explanation:
3x + y = -1
2x + y=0
Subtract to eliminate y:
3x - 2x + y - y = -1 - 0
x = -1
So, substituting for x in the first equation;
3(-1) + y = -1
y - 3 = -1
y = 2.
The solution is the ordered pair (-1, 2).
The system is a pair of straight lines which intersect at the point (-1, 2).
Answer:
I suppose it should be
6b² and (6b²)²
or
6b² and 36
Step-by-step explanation:
(a+b)² = a² + 2ab + b²
therefore
(6b²+2a)² = (6b²)² + 12ab² + 4a²
Answer:
Step-by-step explanation:
We'd solve the exponents first:
Subtract:
7776 - 1296 = 6480
Divide:
We already know
