What is the standard form of y - 8 = 2(x + 3)?
a. 2x - y = -14
b. 2x + y = 14
c. y = 2x + 14
d. y - 2x = 11

A. 2x - y = -14

Step-by-step explanation:The standard form of a linear equation is

Ax + By = C

So we can solve for C, the constant

y - 8 = 2(x + 3)

y - 8 = 2x + 6

y = 2x + 14

-2x + y = 14  

2x - y = -14 (multiply both sides by -1 to keep x positive)

the perimeter is increased by a factor of 2

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
