1/5(10x−15)=1/4(12x−8)

1/5(10x−15)=1/4(12x−8)

Simplify:

(1/5)(10x)+(15)(−15)=(1/4)(12x)+(1/4)(−8)(Distribute)

2x+−3=3x+−2

2x−3=3x−2

Subtract 3x from both sides.

2x−3−3x=3x−2−3x

−x−3=−2

Add 3 to both sides.

−x−3+3=−2+3

−x=1

Divide both sides by -1.

−x/−1 = 1/−1

x=−1

Answer:

$x=11$

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

so

In this problem

$(x+5)=\frac{1}{2}(3x-1)$

solve for x

Multiply by 2 both sides

$2x+10=3x-1$

subtract 2x both sides

$10=3x-1-2x$

$10=x-1$

Adds 1 both sides

$x=11$
