I think you posted this question more than once..
8x - 4y = -12
4y = 8x + 12
y = 8/4 x + 12/4
y = 2x + 3
When x = -3,
y = 2(-3) + 3 = -6 + 3 = -3
When x = -1,
y = 2(-1) + 3 = -2 + 3 = 1
When x = 1,
y = 2(1) + 3 = 2 + 3 = 5
Answer:
1/15 L
Step-by-step explanation:
1/5 x 3
1 x 1 is numerator
5 x 3 are the denominators
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
