Are there any answer choices
5x + 4y ≤ 20
5x - 5x + 4y ≤ 20 - 5x
<u>4y</u> ≤ <u>20 - 5x</u>
4 4
y ≤ 5 - 1.25x
We are given the equation:
cy – 7 = 5d
And we are asked to find for y.
First step, add 7 on both sides:
cy – 7 + 7 = 5d + 7
cy = 5d + 7
Next step, divide both sides by c:
cy / c = (5d + 7) / c
<span>y = (5d + 7) / c</span>
Use x+2y=8
Subtract 2y to make
x=8-2y
Plug this in to the other equation
3(8-2y)+2y=6
Distribute the 3
24-6y+2y=6
Combine like terms
24-4y=6
Solve
18/4=y, 9/2=y
Plug and solve for x
X+2y=8
X+(2*9/2)=8
X+9=8
X=-1
