Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11

y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5

Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6

3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11

y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5

I hope this helps! Let me know if you need me to explain why I did some things :)

Select all the terms that are like terms.
timama [110]

Answer:

-8 x2

1.25 x2

x2

Step-by-step explanation:

Like terms are those which have the same variable. For example x²= x ² but x³≠x² functions having the same variable are called like terms. Terms vary with the change in exponents.

-8 x2

1.25 x2

x2

These three are like terms because they have the same variable with the same exponent.

The following are not like terms. They are unlike terms each having a different variable with a different exponent.

5 yx2

-3.4 x3

4 x

5

Like terms         -8 x2       1.25 x2          x2

Unlike terms :5 yx2             -3.4 x3           4 x                   5
