Answer:
x=-5
Step-by-step explanation:
25 - 3x = 40
-3x + 25 =40
-3x +25--25=40-25
-3x=15
-3x÷-3=25÷-3
x=-5
Answer:
a
Step-by-step explanation:
3/4 x - 3 = -18
You should try to get all of one term on one side of the equation, and have the constant on the other side so the next step would be easy.
Here are the steps after you add 3:
3/4 x = -15
x = -5/4 (divide by 3/4 on both sides)
Answer:
y = 
x - 4
Step-by-step explanation:
Given
4x - 3y = 12 ( subtract 4x from both sides )
- 3y = - 4x + 12 ( divide terms by - 3 )
y = - 4 ← in the form y = mx + b
