Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
Answer:
m=-5/2
Step-by-step explanation:
Use the slope-intercept form y=mx+b to find the slope m.
Youll need to provide more information
4x+12y=48
12y=48-4x
Y=4-3x
Steps
1.subtract 4x to the other side
2.divide 12 to all numbers
Answer is : y=4-3x
