If in the question it is 7x^2 and 3x^2, then

7x^2 - 4x + 10 + 3x^2 - 8

Re grouping the variables,

7x^2 + 3x^2 - 4x + 10 - 8

10x^2 - 4x + 2

The above would be the answer if the question was 7x^2 - 4x +10 +3x^2 - 8

liberstina [14]

Answer:

Step-by-step explanation:

12 (x + 2) - 4x = 4 (2x + 11) - 20

12 + 24 - 4x = 8x + 44 - 20

36 - 4x = 8x + 24

36 - 24 = 8x - 4x

12 = 4x
