Part 2:
-4a + 2 + 11a = 5a + 3 + 2a
~Combine like terms
7a + 2 = 7a + 3
~Subtract 2 to both sides
7a = 7a - 1
~Subtract 7a to both sides
0 = 1
Therefore, there are no solutions.
Best of Luck!
Answer:
63
Step-by-step explanation:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70.
9, 18, 27, 36, 45, 54, 63, 72, 81, 90.
A:63
-1 is the slope
x = 5
6(3 - 7x) = -192
Divide each side by 6
6/6(3 - 7x) = -192/6
3 - 7x = -32
Subtract 3 from each side
3-7x-3 = -32-3
-7x = -35
Divide each side by -7
-7x/-7 = -35/-7
the answer is C.) 7/ 12
(x, y) = (8, 6)
given the 2 equations
2x - y = 10 → (1)
2x - 2y = 4 → (2)
rearrange equation (1) expressing y in terms of x
y = 2x - 10 → (3)
Substitute y = 2x - 10 in equation (2)
2x - 2(2x - 10) = 4
2x - 4x + 20 = 4
- 2x + 20 = 4 ( subtract 20 from both sides )
- 2x = - 16 ( divide both sides by - 2 )
x = 8
substitute x = 8 in equation (3)
y = (2 × 8) - 10 = 16 - 10 = 6
solution is (8 , 6)
