5x+2y=9
Move variable to the right side and change
It’s side.
5x=9-2y
Divide both sides of the equation by 5
X = 9/5 - 2/5y
Final solution
Answer: x = 9/5 - 2/5y
<span>8x + 5 = 35
------------------
Subtract 5 from each side
</span><span><span>8x + 5 - </span>5 </span>= <span>35 - 5
</span><span>8x </span>= <span>30
</span>-----------------------------
Divide each side by the number 8
8x ÷ 8 = 30 ÷ 8
x = 15/4 or 3.75 or 3 3/4
Answer:
Step-by-step explanation:
Equation: y=mx+b
m is the gradient while b is the y-intercept
Let's first find the slope (also known as the gradient) by choosing two points.
The formula to find the slope is change in y divided by change in x.
So two points are: (-2,0) and (0,5)
Change in y: 5-0 (we use the y-coordinates)
Change in x: 0--2 (0+2) (we use the x-coordinates)
So: 5-0= 5 and 0+2= 2 which means 5 divided by 2
Slope= 5 over two
To find the y-intercept we need to see where the line crosses the y-axis which would be at (0,5)
So: y-intercept is 5 as that's where the line crosses the y-axis.
Equation now: y= 5 over 2x +5
