Question

I need help for solving y in this problem 2x -y =1​

Answer 1

Answer:

y = 2x - 1

Step-by-step explanation:

Given equation: 2x - y = 1

We're being asked to solve for y. This is also known as the Slope-Intercept Form. It is represented by the following formula:

y = mx + b

where:

• m is the slope
• b is the y-intercept (when x = 0)

Steps:

1. Subtract 2x from both sides:

$\sf 2x-2x - y = 1-2x\\\\\implies-y=-2x+1$

2. Divide both sides by -1:

$\sf \dfrac{-y}{-1}=\dfrac{-2x+1}{-1}\\\\\implies y=2x-1$

This equation has a slope of 2, and a y-intercept of -1.
