How do you solve 2x plus 1 equals 3y and 4 equals 3y-10 by elimination?
1) 2x + 1 = 3y
2) 4 = 3y - 10 this can be re-written as 3y = 4 + 10
Therefore 2x + 1 = 4 + 10
2x = 13
x = 6.5
Sustitute x = 6.5 in equation 1) above
2x + 1 = 3y
2 (6.5) + 1 = 3y
therefore 3y = 13 +1
3y = 14
y = 14/3
Now substitute y = 14/3 in equation 2) above and watch what happens!
4 = 3(14/3) -10
4 = 4
Therefore the answer is correct!
What is -3x-7 plus x-9 simpifed?
The expression reads as this:
-3x-7+x-9
Combine like terms.
-3x+x-7-9
-2x-16
If you would like to factor the expression, you can take out the coefficient -2, giving you
-2(x+8).

What will be the next 3 numbers of 50 52 56 and 62?
It is 70.
You keep adding even numbers (in the usual order) to the number.
For example, 50+2=52. The next even number is 4 and so, 52+4=56. Similarly, 56+6=62. The next even number is 8 and therefore, 62+8=70 and that's you answer.
Is isosceles triangle also an equilateral triangle?
An equilateral triangle has all sides measuring the same and an isosceles triangle has 2 sides congruent, so they are not the same.
Every equilateral triangle is also an isosceles triangle, but not every isosceles triangle is an equilateral triangle.
Isosceles = at least two equal sides
Equilateral = three equal sides
X x is a real number such that x² equals 4?
it is because the X means times and the other x means a mystery number.
example 2 X x = 78
the answer can be anything unless you really study the number until u find out what number it is it helps if u do this:
8
2 2
x this x is 8 because the opposite one is 8
