Answer:(-2, 2)

Step-by-step explanation:

7q² - 28 = 0

Add 28 to bothside

7q² - 28 + 28 = 0+ 28

7q² = 28

Divide bothside by 7

7q² / 7 = 28/7

q² = 4

Take the square root of bothside

√q² = ±√4

q = ± 2

q = -2 or q =2

q = (-2, 2)

allsm [11]

Answer:

Here,

$2x + 4y = 16....eqn \: i \\ 4y = 12....eqn \: ii$

substituting the value of 4y in eqn i fron eqn ii

so eqn i becomes

$2x + 12 = 16 \\ 2x = 4 \\ x = 2$

$y = 12 \div 4 = 3$

Thus,

$x = 2 \: and \: y = 3$
