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:
a = 0, b = 7
a = 1, b = 6
a = 2, b = 5
a = 3, b = 4
a = 4, b = 3
a = 5, b = 2
a = 6, b = 1
a = 7, b = 0
Step-by-step explanation:
the sum of a and b must equal 7 because 4 x 7 = 28
Just combine everything
