150 = 8x + 6y 

solve for X ​

y=25

Step-by-step explanation:

150=8x+6y

150=8(0)+6y

150=6y

divided by 6 on both sides because what you do to one side you have to do to the other side.

then your left with y=25

Simplifying

150 = 8x + 6y

Solving

150 = 8x + 6y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

150 + -8x = 8x + -8x + 6y

Combine like terms: 8x + -8x = 0

150 + -8x = 0 + 6y

150 + -8x = 6y

Add '-150' to each side of the equation.

150 + -150 + -8x = -150 + 6y

Combine like terms: 150 + -150 = 0

0 + -8x = -150 + 6y

-8x = -150 + 6y

Divide each side by '-8'.

x = 18.75 + -0.75y

Simplifying

x = 18.75 + -0.75y

Step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
