solve y - 3x = 13 for y
Y=3x+13
Solve 2x+y=7 for y.
To solve for y in the equation y - 3x = 13, we need to isolate the y variable on one side of the equation. Here's how:
Step 1: Start with the equation: y - 3x = 13
Step 2: Add 3x to both sides of the equation to eliminate the -3x term on the left side:
(y - 3x) + 3x = 13 + 3x
y - 3x + 3x = 13 + 3x
Simplifying the left side:
y + 0 = 13 + 3x
y = 13 + 3x
Therefore, the solution for y is y = 13 + 3x.
