Step-by-step explanation:
3/7y + 3/4x = 3/5
y = -3/4x.7/3 +3/5.7/3
y = -7/4x +7/5
so the slope is -7/4
So, 5 x (-3) + 7 = -15 + 7 = - 8 , but not 4;
Then, -3 is not a solution to 5x + 7 = 4;
Answer: -4
Step-by-step explanation:
Do -6 x 2 to get -12, then divide by 3 to get -4
Thats assuming this is a fraction and not an actual division sign
Note that 5x appears on both sides of this equation. Delete 5x from each side. This leaves us with 3x = 15/2. Dividing both sides by 3 results in x = 5/2 (ans)
