Solve this equation for y. <br> 3x - 5y = 12
Volgvan
-5y=12-3x (subtract 3x from both sides)
y = - 12-3x/5 (divide both sides by -5)
y = - 3(4-x)/5 (common term is 3)

What algebraic expression represents GK?
dsp73

Answer:

Part a) GK=(7x+1)

Part b) GH=5 units and JK=8 units

Step-by-step explanation:

Part a) what algebraic expression represents GK?

we know that

GK=GH+HJ+JK

step 1

Find GH

we have

GH=GJ-HJ

substitute the given values

GH=(2x+3)-x=x+3

step 2

Find JK

JK=HK-HJ

substitute the given values

JK=(6x-2)-x=5x-2

step 3

Find GK

GK=GH+HJ+JK

we have

GH=x+3

HJ=x

JK=5x-2

substitute

GK=(x+3)+x+(5x-2)

GK=(7x+1)

Part b) If GK=15, what are GH and JK?

we know that

GK=(7x+1)

For GK=15

substitute the value of GK and solve for x

15=(7x+1)

7x=15-1

7x=14

x=2

<u><em>Find the value of GH</em></u>

GH=x+3

substitute the value of x

GH=2+3=5 units

<u><em>Find the value of JK</em></u>

JK=5x-2

substitute the value of x

JK=5(2)-2=8 units
