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!
Answer:
Combine like terms; 3x + 5x= 8x
Since you don't have any like terms for +8, it's going to remain the same and not change.
Answer : 3x + 5x + 8 = 8x + 8
Again with combining like terms, 4x + 4x = 8x
Answer: 4x + 4x = 8x
The third expression is going to be very similar to the last problem. 4x + 4x + 4x + 4x. We're going to add the terms together. 4+4+4+4 is equal to 16. Bring the x down and you get...
Answer: 16x
Lastly, we have -7x + 4 + 3x. Do the exact same thing we did to the other problems, combining like terms, shocking, I know. -7x + 3x= -4 and since there's no other like terms for +4, it stays the same. Therefore
Answer: -7x + 4 + 3x = -4 + 4

Answer:
15 x 30
Step-by-step explanation:
Distribute -5 to each variable in the parenthesis.
-5 x -3 = 15
-5 x -6 = 30
