Answer:
The answer is A.
Step-by-step explanation:
Answer:
x = -2, y = 2
Step-by-step explanation:
-7x + 7y = 28
7y = 28 + 7x
y = 4 + x ----(1)
-8x+4y=24 -----(2)
sub (1) into (2)
-8x+4(4+x)=24
-8x+16+4x = 24
-8x+4x = 24-16
-4x = 8
x = -2
sub x = -2 into (1)
y=4+(-2) = 2
Answer:
The answer is (A)
Step-by-step explanation:
Answer:
18x - 12
Step-by-step explanation:
multiply each term in the parenthesis by the 6 outside ( distributive law)
6(3x - 2)
= (6 × 3x ) + (6 × - 2) = 18x +(- 12) = 18x - 12
