What is 3x+70=8x-20 show work

Mathematics
1 answer:
Elena-2011 [213]3 years ago
6 0

Answer:

Hi there!

Your answer is:

x= 18

Step-by-step explanation:

3x+70=8x-20

Isolate x on left side

3x+70=8x-20

-8x       -8x

-5x +70 = -20

Isolate whole numbers on right side

-5x +70 = -20

      -70      -70

-5x = -90

Isolate x by dividing both sides by -5

-5x = -90

/-5

x= 18

What is the equation of the line that passes through the point (−0.5,8) and has a slope of −5?
natima [27]

Answer:

Slope=-1.8, X=-0.5, y=1.9

Equation is y^2-y^1=m(x^2-x^1).

Y-1.9=-1.8(X-(-0.5))

Y-1.9=-1.8x+0.90

Add 1.9 on both sides.

Y= -1.8x+1.

I hope this helps you.
