Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
![- x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3](https://tex.z-dn.net/?f=%20-%20x%20%2B%201%20%3D%204x%20-%2014%20%5C%5C%20%20-%20x%20-%204x%20%3D%20%20-%2014%20-%201%20%5C%5C%20%20-%205x%20%3D%20%20-%2015%20%5C%5C%20x%20%3D%203)
Substitute x = 3 in any given equations. I will do in y = - x + 1
![y = - x + 1 \\ y = - 3 + 1 \\ y = - 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20x%20%2B%201%20%5C%5C%20y%20%3D%20%20-%203%20%2B%201%20%5C%5C%20y%20%3D%20%20-%202)
Therefore the answer is (3,-2)
Answer:
60
Step-by-step explanation:
45 divided by 9 is 5. So you multiply 4 times 5. Which equals 20. So 20 plus 45 is 65. Hope you understand it.
hey there
the answer is
14x + 6 = 5x + -3
6 + 14x = 5x + -5
6 + 14x = -3 + 5x
6 + 14x + -5x = -3 + 5x + -5x
Combine like terms: 14x + -5x = 9x
6 + 9x = -3 + 5x + -5x
Combine like terms: 5x + -5x = 0
6 + 9x = -3 + 0
6 + 9x = -3
6 + -6 + 9x = -3 + -6
Combine like terms: 6 + -6 = 0
0 + 9x = -3 + -6
9x = -3 + -6
Combine like terms: -3 + -6 = -9
9x = -9
Divide each side by '9'.
x = -1
Simplifying
x = -1
thank you
