Which equation shows y=-12x+4 is in standard form?

A. 2x + y = 8

B. x + 2y = 8

C. 2x-y=8

b

Step-by-step explanation:

Solution:

y = - (1/2) x+4

Standard form of the equation Ax+By=C, with A, B, and C integer numbers

The coefficient of x is a fraction. To simplify the fraction, let's multiply both sides of the equation by 2:

2y=2 [ - (1/2) x+4]

2y=-2 (1/2) x+2 (4)

2y = - (2/1) (1/2) x+8

2y=-[ (2*1) / (1*2) ]x+8

2y = - (2/2) x+8

2y=-1x+8

2y=-x+8

The two variables must be on the left of the equation, then adding x both sides of the equation:

2y+x=-x+8+x

x+2y=8
