Solve the system of equations.<br> y= 3x +5<br> y= 8x +3

Lady bird [3.3K]

Answer:

y=6.2 and x=0.4 or (0.4,6.2)

Step-by-step explanation:

Since both expressions are equal to y, we can set them equal to each other and solve for x:

3x+5=8x+3

5=5x+3

2=5x

2/5=x

0.4=x

Now to solve y:

y=8(2/5)+3

y=16/5+3

y=3.2+3

y=6.2

Check answers:

6.2=3(0.4)+5

6.2=1.2+5

6.2=6.2

6.2=8(0.4)+3

6.2=3.2+3

6.2=6.2

Answers work, so y=6.2 and x=0.4 or (0.4,6.2) as an ordered pair

Change the line 3x − 8y = 5 into slope-intercept form.

Nimfa-mama [501]

Slope is y=mx+b
m=slope
b=y intercept

solve for y basically

3x-8y=5
minus 3x both sides
-8y=-3x+5
divide both sides by -8
$y=\frac{3}{8}x-\frac{5}{8}$
