Answer:
x = 7
y = -3
Step-by-step explanation:
x + y = 4 (Multiply this by 9)
-9x + 7y = -84
9x + 9y = 36
-9x + 7y = -84
16y = -48
y = -3
x + y = 4
x - 3 = 4
x = 7

Answer:
147
Step-by-step explanation:
We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:
a² + √b
12² + √9
The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.
144 + 3 = 147
The answer is thus 147.
