1.solve for y
 2x+4y=12      
<u>  </u><span><u> -2x       -2x</u>
</span><u>4y</u>=<u>12-2x</u>
<u>4       4</u>
y=3-1/2x

step2 plug in y and solve for x
2x+8y=24
2x+8(3-1/2x)= 24
2x+24-4x=24
<u>-2x</u>=<u>0
</u><u>-2    -2</u>
 x=0
last step plug in x and solve for y

y=3-1/2x(0)
y=3

A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were tripled what would be the
vagabundo [1.1K]
Originally we have
length = x
width = x-2
since the width is 2 inches smaller than the length

now let's triple each dimension. Multiply the expressions by 3 to get
new length = 3*x
new width = 3*(x-2) = 3x-6

Now onto the area
area = (length)*(width)
area = (3x)*(3x-6)
area = 3x*3x-3x*6
area = 9x^2 - 18x

So the new larger rectangle has area of 9x^2-18x
