marta [7]

S= number of small boxes
l= number of large boxes

equation 1: s+l=120
equation 2: 15s+45l=3300

solve by elimination, multiply equation 1 by -15.

-15(s+l=120) = -15s-15l=-1800 add to equation 2.

-15s+15s-15l+45l=-1800+3300 = 30l=1500

30l=1500 , l=50

s+l=120, s+50=120 --> s=70

Solve: 28 − ≥ 7( − 4) (show your work) real answers only pls :(

ohaa [14]

You’ll distribute the 7 from (x-4) so your equation will be
28-x>_ 7x-28
then you’ll combine like terms (-x and 7x and 28 and -28
-56>_ -8x
divide by -8 on both sides and flip your sign
you’re answer is x<_7
x is less then or equal to 7

Solve for (y)(x) x-y=1 1/2x+y=5

TEA [102]

Using addition

x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
$\frac{3}{2}x=6$
3x=12
x=4

Using the value of x
x-y=1
4-y=1
y=3

With x as 4 and y as 3, their product is 12
And can be written as (4,3)
