Answer:
y = 1, x = - 8
or
(-8, 1)
Step-by-step explanation:
-x + 4y = 12
x + y = -7
add the equations together
0x + 5y = 5
5y = 5
y = 1
substitute y for 1 in one of the original equations to find x
x + y = -7
x + 1 = -7
x + 1 - 1 = - 7 - 1
x = - 7 - 1
x = -8
Answer:
78
Step-by-step explanation:
Find the prime factorizations of the two numbers:
26 = 2 * 13
39 = 3 * 13
The LCM is the product of common and not common factors with the higher exponent.
LCM = 2 * 3 * 13 = 78
