Answer:
p=16
Step-by-step explanation:
7(x+2)= 7x + 14
7x + 14 = 7x + 14
A.
(7^2)^x = 1
(49)^x = 1
thus x = 0
B.
<span>(7^0)^x=1
(1)^x = 1
thus x can be any real number.

Answer:
x = 1
Step-by-step explanation:
<u>Step 1: Choose one of the equations to solve for y:</u>
x - y + 1 = 0
(-y) / -1 = (-1 - x) / -1
y = 1 + x
<u>Step 2: Plug in y into either equation</u>
3x + 2(1 + x) = 7
3x + 2 + 2x - 2= 7 - 2
5x / 5 = 5 / 5
x = 1
Answer: x = 1
