To solve this system of equations using substitution, what could be substituted in place of y in the first equation? 4x = 5 − 2y

erik [133]

Answer:

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

Step-by-step explanation:

Step 1: Switch sides

5 - 2y = 4x

Step 2: Subtract 5 from both sides

5 - 2y - 5 = 4x - 5

Step 3: Simplify

-2y = 4x - 5

Step 4: Divide both sides by -2

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

Step 5: Simplify

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