Ответ:
B
Step-by-step explanation:
Put the second y into the first equation
3x + y = 10 substitute for y
3x + 6x + 1 = 10 Combine like terms on the left
9x + 1 = 10 Subtract 1 from both sides
9x = 10 - 1 Combine the right.
9x = 9 Divide by 9
x = 9/9 Divide
x = 1
The answer is right there. Only B is possible
y = 6x + 1
y = 6(1) + 1
y = 6 + 1
y = 7
Answer B
