Y-2x=8 (label equation 1)
16+4x=2y (label equation 2)

divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8

once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of

KiRa [710]

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

$\frac{L}{W}=\frac{5}{3}$

Where:

L represents the new length
W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

$L=18-x$

$W=12-x$

Then, we will have:

$\frac{18-x}{12-x}=\frac{5}{3}$

Finally, we just need to solve it for x.

$3(18-x)=5(12-x)$

$5x-3x=60-54$

$2x=6$

$x=3$

<u>Therefore, the value of </u><u>x = 3.</u>

I hope it helps you!
