Question

ve the system by substitution.
$2x + 2y = 50$
$y = 4x$
answer attempt 1 out of 2

Explanation:

Step1: Substitute $y=4x$ into first equation

$2x + 2(4x) = 50$

Step2: Simplify and solve for $x$

$2x + 8x = 50$
$10x = 50$
$x = \frac{50}{10} = 5$

Step3: Find $y$ using $y=4x$

$y = 4\times5 = 20$

Answer:

$(5, 20)$
