Answer:
x=
1/2
and y=3
Step-by-step explanation:
Let's solve your system by substitution.
y=10x−2;2x+y=4
Step: Solvey=10x−2for y:
y=10x−2
Step: Substitute10x−2foryin2x+y=4:
2x+y=4
2x+10x−2=4
12x−2=4(Simplify both sides of the equation)
12x−2+2=4+2(Add 2 to both sides)
12x=6
12x
12
=
6
12
(Divide both sides by 12)
x=
1
2
Step: Substitute
1
2
forxiny=10x−2:
y=10x−2
y=10(
1
2
)−2
y=3(Simplify both sides of the equation)
Answer:
x=
1
/2
and y
The fraction

To find this we need to realize that .66 can be converted to a fraction. The last 6 is in the hundredths place, so if we convert .66 to a fraction we will get:

If we simplify this fraction as much as we can, we will get to

To check this we can divide

. So, 2 ÷ 3 = .66, which is correct, so our answer is correct.
I hope this helped! Have an amazing day :)
Clever !
The two square roots of 50 will do that.
They are irrational numbers, so I can't write down their exact values.
They are approximately +7.0711 and -7.0711 (rounded) .
