the question does not present the options, but this
does not interfere with the resolution
Let
x--------> the number of color copies
y-------> the number of black-and-white copies
we know that
x+y=6--------> equation 1
3x+y <=12------> equation 2
using a graph tool
see the attached figure
the solution is the triangular shaded region
<span>-8(4 + 9x) = 7(-2 -11x)
STEP 1: Simplify both sides of the equation.

STEP 2: Add 77x to both sides.

STEP 3: Add 32 to both sides.
</span></span></span><span><span><span><span>5x</span>−32</span>+32</span>=<span><span>−14</span>+32</span></span><span><span>5x</span>=<span>18
STEP 4: Divide both sides by 5.
5x/5 = 18/5
x = 18/5
YOUR FINAL ANSWER: x = 18/5</span></span>
Answer:
Step-by-step explanation:
The graph increases because it rises from point D to G.
Answer: 6x=42
Explanation: After the step 6x+6=36, it’ll equal 6x=30 because when you subtract the 6 on both sides, it’ll equal 30, revealing it’s actually 6x=30, with the conclusion of x=5.
