Solve:
x+x=0
3y+(-2)=7
3y+(-2)=7
3y-2=7
y=3
x+x=0
2x=0
x=0
i thought that was the answers
To solve the equations:
1) x + x = 0
To solve this equation, we simplify and combine like terms. Adding x to x gives us 2x. Therefore, the equation becomes:
2x = 0
Next, we need to isolate x by dividing both sides of the equation by the coefficient of x, which is 2:
2x / 2 = 0 / 2
x = 0
So the solution to the equation x + x = 0 is x = 0.
2) 3y + (-2) = 7
To solve this equation, we start by simplifying the expression on the left side of the equation. The sum of 3y and -2 is:
3y - 2
So the equation becomes:
3y - 2 = 7
Next, to isolate y, we add 2 to both sides of the equation:
3y - 2 + 2 = 7 + 2
3y = 9
To solve for y, we divide both sides of the equation by the coefficient of y, which is 3:
(3y) / 3 = 9 / 3
y = 3
So the solution to the equation 3y + (-2) = 7 is y = 3.
