-10(10x-12)=-9(-9x-2)-5
Viefleur [7K]

10(10x−12)=−9(−9x−2)−5
Step 1: Simplify both sides of the equation.
−10(10x−12)=−9(−9x−2)−5
(−10)(10x)+(−10)(−12)=(−9)(−9x)+(−9)(−2)+−5(Distribute)
−100x+120=81x+18+−5
−100x+120=(81x)+(18+−5)(Combine Like Terms)
−100x+120=81x+13
−100x+120=81x+13
Step 2: Subtract 81x from both sides.
−100x+120−81x=81x+13−81x
−181x+120=13
Step 3: Subtract 120 from both sides.
−181x+120−120=13−120
−181x=−107
Step 4: Divide both sides by -181.
−181x
−181

Whats the order pair of x,y for x-2y=-12 x 6y=20?
mote1985 [20]
X-2y=-12
x+6y=20
we can cancel x's
multiply first equation by -1 and add to 2nd equation

-x+2y=12
<u>x+6y=20 +</u>
0x+8y=32

8y=32
divide both sides by 8
y=4

sub back

x-2y=-12
x-2(4)=-12
x-8=-12
add 12 both sides
x=-4


(x,y)
