Answer:
35
Step-by-step explanation:
I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.
So we have = 21
When it comes to equations with a variable, our goal is to isolate the variable, so let's start.
= 21
1. Combine multiplied terms into a single fraction :
= 21
2. Multiply both sides by the denominator :
5 * 3/5 = 3
5 * 21 = 105
3x = 105
3. Divide both sides by 3 :
x = 35

Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
