(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6.
Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9
Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(:
Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!

Does (-2x+y=6)+ (y-2x=4) have no solution?

DedPeter [7]

Assuming you are asking

does -2x+y=6 and y-2x=4 have a solution

look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values

there is no solution
these 2 lines are paralell

The area of a rectangle is 300 square centimeters. If the sides of the rectangle are given as 5 centimeters and <img src="https:

joja [24]

<em>x</em> is 1000, and the other side of the rectangle is 60 cm.
Area is found by multiplying length by width. Using the sides we know we have
$300=5(\sqrt{x+2600})$
We divide both sides by 5:
$\frac{300}{5}=\frac{5\sqrt{x+2600}}{5}
\\
\\60=\sqrt{x+2600}$
To "undo" a square root, we square both sides:
$60^2=(\sqrt{x+2600})^2
\\
\\3600=x+2600$
Subtract 2600 from both sides:
3600-2600=x+2600-2600
1000=x
Now we substitute this into the side with x:
$\sqrt{x+2600}=\sqrt{1000+2600}=\sqrt{3600}=60$
