Answer:
14x+7 = 30
Step-by-step explanation:
7y +6 = 36
y = 2x+1
Substitute the second equation into the first for y
7(2x+1) +6 =36
Distribute
14x+7 +6 = 36
14x+13 =36
Subtract 6 from each side
14x+13 -6 = 36-6
14x+7 = 30
Answer:
A
Step-by-step explanation:
7y + 6 = 36
7(2x + 1) + 6 = 36
14x + 7 + 6 = 36
14x + 13 = 36
14x + 13 - 6 = 36 - 6
14x + 7 = 30
