3x + y = 7 for y
y=7-3x
6-2(x+7)=10-24
To find the value of y in the equation 3x + y = 7, we need to isolate y on one side of the equation.
Step 1: Start with the given equation: 3x + y = 7.
Step 2: Subtract 3x from both sides of the equation to move the term with the x variable to the other side:
3x + y - 3x = 7 - 3x.
This simplifies to: y = 7 - 3x.
Therefore, the value of y in the equation 3x + y = 7 is y = 7 - 3x.
