Answer:
use the subtraction property of equality to subtract 3x from both sides of the equation
Step-by-step explanation:
y is on the left so move everything else to the right side
According to the Subtraction Property, both sides of an equation remain equal following a subtracting of the same amount from both sides of the equation
The first step in isolating y in the equation 3·x + 2·y = 4 is the option;
- Use the Subtraction Property of Equality to Subtract 3·x from both sides of the equation
Reason:
The slope and intercept form of the straight line equation is the the equation in the form y = m·x + c
Where;
m = The slope of the equation
c = The y-intercept
The given equation is 3·x + 2·y = 4
To isolate y, the terms containing y, are placed on one side of the equation, while the other terms are placed on the other side as follows;
First step; 3·x + 2·y - 3·x = 4 - 3·x (Subtraction property of equality)
Second step; 2·y = 4 - 3·x
Third step; [tex]\dfrac{2 \cdot y}{2} = \dfrac{4 - 3 \cdot x}{2}[/tex] → y = 2 - 1.5·x (Division property of equality)
y = 2 - 1.5·x = -1.5·x - 2
y = -1.5·x - 2 Equation in slope and intercept form
Therefore, the first step is use the Subtraction Property of Equality to Subtract 3·x from both sides of the equation
