Answer:
x = - 12/11
Step-by-step explanation:
Multiply by LCM (or LDC if you like that term better)
2 & 3 LCM = 6
6(3/2) x + 6(1/3)x + 5*6 = 3*6
9x + 2x + 30 = 18
11x = - 12
x = - 12/11
Answer:
2x + 8
Step-by-step explanation:
Don't worry, this is simple! Add up the common terms.
For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.
So combine the x terms: 2x
And the numerical terms: 8
Combine 2x and positive 8.
2x + 8
[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5
