I need help with 8x+3-10=-2 (x-2)+3
astraxan [27]

0 ≠ 4. The equation is wrong, and has no true solution.

8x + 3 - 10x = -2(x - 2) + 3

<em><u>Distributive property.</u></em>

8x + 3 - 10x = -2x + 4 + 3

<em><u>Combine like terms.</u></em>

-2x + 3 = -2x + 7

<em><u>Cancel like terms.</u></em>

<em><u>Subtract 3 from both sides.</u></em>

0  ≠ 4

We have that when the sides are congruent that is to say that they have the same direction and the same size and also the two opposite sides are parallel, the angles will be the same.

Now, in an isosceles triangle, two angles are congruent, because their two sides are congruent.
