9 + 5x- 5 + 3x = 4+8x = 4(1+2x)
2x+9-x+3 = x+12
7x+5-2x+8 = 5x +13
combine like terms and add and subtract
hope this helps XD have a wonderful break
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
x + 2y = 14 ...............(1)
6x + 3y = 21 ..............(2)
Solve for x in equation 1
When x + 2y = 14
Therefore x = 14 - 2y ...................(3)
Now put equation 3 in equation 2 and solve
6x + 3y = 21 .............(2)
6(14 - 2y) + 3y = 21
Open the bracket and resolve
84 - 12y + 3y = 21
-9y + 84 =21
Now collect the like terms
-9y + 84 = 21
-9y = 21 - 84
-9y = -63
Divide through by -9 to get y
y = -63/-9
y = 7
Substitute for y in equation( 3 )to x
x= 14 - 2y............(3)
So, x = 14 - 2(7)
x = 14 - 14
x = 0.
Therefore x = 0 and y = 7
Check: From equation (1)
x + 2y = 14
Now, put x = 0 and y = -2
Therefore, 0 +2(7) =14
0 +14 = 14
For this case we have the following equation:
We must solve the equation by following the steps below:
We subtract 1 from both sides of the equation:
On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:
We add x to both sides of the equation:
We divide between 4 on both sides of the equation:
Thus, the correct option is option B
