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

5x-10x+ 2(3y-2)= 10y-5x + 4
Bas_tet [7]
5x-10x+ 2(3y-2)= 10y-5x + 4

Multiply 2 x 3y and by -2

5x-10x+6y-4=10y-5x+4

You get 6y-4

-5x+6y-4=10y-5x+4

Subtract 10x from 5x to get -5x

6y-4=10y+4

Add 5x to the -5x

6y=10y+8

Add 4 to the other side to get 8

-4y=8

Subtract 6y-10y to get -4y

-4y/-4=8/-4

Divide -4y and 8 by -4 to get y by itself and -2

Y=-2
