Mathematics

Y = 2x + 5
(7,1)...x = 7 and y = 1
now we sub
1 = 2(7) + 5
1 = 14 + 5
1 = 19...incorrect....NO (7,1)  is not a solution

***now if there was a typo and ur set of points are (1,7)
y = 2x + 5
7 = 2(1) + 5
7 = 2 + 5
7 = 7...correct....so (1,7) is a solution

3(x+2)-2(×+1) i need help with this problem
zhuklara [117]

Question:

What is 3(x + 2) - 2(x + 1)?

Steps:

When you solve this type of equation always use the distributive property formula to solve this equation!

Formula: a(b + c) = ab + ac

So, what is 3(x + 2) ?

  • 3x + 6

Also, what is -2(x + 1)?

  • -2x - 2

Then, put it back into the equation for you to solve this problem.

So, this would be the new equation:

3x + 6 - 2x - 2

Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:

3x - 2x + 6 - 2

Then, simplify:

x + 4 is the answer!

Since 3x - 2x = x and 6 - 2 = 4


Hope that helped!!
