Question

What is the first step in solving the equation 4x+2y=5 for x

Answer 1

Explanation:

Slope-intercept form: → $y=mx+b$

m: represents the slope and is constant.

b: represents the y-intercept.

Rise/run.

$\frac{rise}{run}$

$m=\frac{rise}{run}$

$m=\frac{y^2-y^1}{x^2-x^1}$

But the slope is -2.

Hope this helps!

Thanks!

Answer 2

Hey there!

Answer = $\frac{-1}{2}y+ \frac{5}{4}$

Explanation:

Let's solve for x.

4x + 2y = 5

Add -2y to both sides:

4x + 2y + -2y = 5 + -2y

4x = -2y + 5

Divide both sides by 4:

$\frac{4x}{4}=\frac{-2y+5}{4}\\\\x=\frac{-1}{2}y+\frac{5}{4}$
