Answer:
<em>-14x+6</em>
Step-by-step explanation:
first, we distribute the -3.
-3(4x - 2) - 2x=-12x+6-2x
than, we conbide like terms
-12x+6-2x=-14x+6
By solving the equation:
4b + 6 = -2
4b = -2 - 6 (taking 6 from each side)
4b = -8
b = -2 (divide both sides by 4)

Answer:
5 dollars
Step-by-step explanation:
Let's call the price of a package of pens n, and the cost of a box of paper r.
3n+r=26
2n+7r=49
Multiply the first equation by 7:
21n+7r=182
Subtract the second equation from the first:
19n=133
Divide both sides by 19 to isolate n:
n=7
Plug this back in to find the value of a box of paper:
3(7)+r=26
21+r=26
r=5
Hope this helps!
