1y + 2x = 0 ⇒ -2x - 1y = 0
4x + 1y = 3 ⇒ <u>4x + 1y = 3</u>
<u>2x</u> = <u>3</u>
2 2
x = 1.5
4(1.5) + y = 3
6 + y = 3
<u>- 6 - 6</u>
y = -3
(x, y) = (1.5, -3)

Answer:
11.33 or 34/3
Step-by-step explanation:
6x+23+9x−13=180
Step 1: Simplify both sides of the equation.
6x+23+9x−13=180
6x+23+9x+−13=180
(6x+9x)+(23+−13)=180
15x+10=180
15x+10=180
15x+10−10=180−10
15x=170

Answer:
y-1=2*(x+2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Sole the power at the bottom, it gives .25
Multiple the whole fraction by 8 to make the denominator match 2
should be 8/2 + 1/2
They are the same denominator so you can add them to make 9/2
Divide it up/simple it up to make 4 and a half, or 4 1/2
