The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

We can substitute y in the second equation with the first equation since y = y. Thesolution of the linear system is (1, 6). You can use the substitution method even if both equations of the linear system are in standard form. Just begin by solving one of the equations for one of its variables.

A triangle has angles that measure 46° and 61° what is the measure of the third angle

Brilliant_brown [7]

A triangle in total is 360°. So you add what you are given

46 + 61 = 107

and subtract that from 360

360 - 170 = 190

And the remainder is the last unknown angle.

So, the third angle is 190°

marshall27 [118]

The numbers that can be expressed in the form of a fraction are called rational numbers. While that numbers that cannot be expressed in the form of a fraction are called irrational numbers.

$\sqrt{45} =\sqrt{3 \times 3 \times 5}$
