Answer:

y=6

x=5

Step-by-step explanation:

multiply first equation by -1

-1 × -6x + 6y =6 ➡ 6x -6y = -6 now add up both equations

6x-6y -6x+3y = -6-12 (6x will be eliminated)

-3y = -18

y=6 use this value to find x

-6x +6×6=6 ➡ -6x = 6 -36 ➡x = 5

FrozenT [24]

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$ , thus

(a + b)² = ( $\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$
