x=10
For the equation -9 - 6x +7x = 1
First, add nine to both sides to get all of the x's on one side
-9 - 6x + 7x = 1
+9 +9
-6x +7x = 10
Then, combine like terms on the left side
-6x+7x=10
x=10
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
7x = -3y + 12
Why not? The statement is trivially true, meaning it holds for all values of x.
7x + 9 = 51 7x = 42 x = 42/7 = 6
Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19
56x^2 + 96x + 40
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
7x - 2 = 60 Add '2' to both sides 7x = 62 Divide both sides by; ;7; # 7x/7 = 62/7 x = 8 6/7 = 857142.....
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
7x = -3y + 12
-10 + 7x + 4x = 78 Collect like terms -10 + 11x = 78 Add '10' to both sides 11x = 88 Divide both sides by '11' 11x/11 = 88/11 x = 8 The answer!!!!!

It is an equation and the value of x is 2
