The answer is five remainder four
When solving equations like these, our number one goal is to get x to be alone.
So given the equation lets go through it step by step.
3x - 5 = 10 + 7x (first step is to add 5 to both sides)
+ 5 = + 5 ( Now lets see what we have now)
3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)
-7x = -7x ( now what do we have?)
-4x = 15 (okay divide both sides by 4 to isolate the x)
÷4 = ÷4 (now the 4's on the left side cancel out, and we solve on the right side)
x = 3.75
That's your answer :) Good Luck!
Answer:
y = -x + 1
Step-by-step explanation:
We are asked to find the equation of a line parallel to
x + y = 3
Step 1: find the slope
x + y = 3
Following the equation of a line
y = mx + c
3 - x = y
-x + 3 = y
y = -x + 3
Slope m = -1
Step 2: substitute m = -1 into the equation
y - y_1 = m( x - x_1)
Using the point ( 0 , 1)
x_1 = 0
y_1 = 1
y - 1 = m( x - 0)
m = -1
y - 1 = -1 ( x - 0)
Open the bracket
y - 1 = -1x + 0
y - 1 = -x
y = -x + 1
The equation of the line is
y = -x + 1
