2x - 2y = -12
- 2y = -2x - 12
y = x + 6
4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9
y = -9 + 6
y = -3
(-9 , -3) is the solution
Answer:
x = 129
Step-by-step explanation:
x and 51 are same- side exterior angles and supplementary, thus
x = 180 - 51 = 129

Answer: 3cm
Explanation:
We can use Pythagorean’s theorem to find that other side:
a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3
Therefore, the other side is 3cm
The answer to this is 3.083
