Estimate the solution to the system of equations 2x+3y=6 -4x+3y=12
1 answer:
Answer:
(x, y) = ( 1, 10/3)
Step-by-step explanation:
2x + 3y + 12
6 - 4x + 3y = 12
Simplify the equation:
2x + 3y = 12
-4x + 3y = 6
Multiply both sides by -1:
2x + 3y = 12
4x - 3y = -6
Eliminate one variable by adding the equations:
6x = 6
Divide both sides by 6:
x = 1
Substitute the value of x into the equation:
-4 x 1 + 3y = 6
Solve the equation:
y = 10/3
A possible solution:
(x, y) = ( 1, 10/3 )
Check the solution:
2 x 1 + 3 x 10/3 = 6 -4 x 1 + 3 X 10/3 = 12
Simplify the expression:
12 = 12 = 12

Answer:
Abdul - 8 messages
Latoya - 16 messages
Dale - 64 messages
Total - 88 messages
Step-by-step explanation:
A: (x)
L: (A + 8)
D: (L* 4)
A: 8 = 8
L: 8 + 8 = 16
D: 16 * 4 = 64
8 + 16 + 64 = 88

(7h)^3
=(7h) (7h) (7h)
=7×7×7×h×h×h

No because in 456.1 it has a 5 in the tens place which is less than the 6 in the tens place in 465.1
