Answer:
Infinite
Step-by-step explanation:
3(4x + 1) - 2
= 12x + 3 - 2 (Multiply the sum in the bracket by 3)
= 12x + 1 (Simplify)
This means that:
12x + 1 = 3(4x + 1) - 2
is the same as
12x + 1 = 12x + 1
Hence, anything that is used to substitute x is correct.

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
