Question

question 5.solve for $y$ in the two equations below using substitution.$2x - 4y = 4$$2x + 4y = 20$a. $y = 6$b. $y = 2$c. $y = 4$d. $y = 3$question 6.chance has hired a construction crew to renovate his kitchen. they square foot for materials and $121.69 per day of labor. chance spent

Explanation:

Step1: Isolate $2x$ from first eq

$2x = 4 + 4y$

Step2: Substitute $2x$ into second eq

$(4 + 4y) + 4y = 20$

Step3: Simplify and solve for $y$

$4 + 8y = 20$
$8y = 20 - 4$
$8y = 16$
$y = \frac{16}{8}$

Answer:

B. $y = 2$
