Answer: 22-4x when you simplify it all.

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

Steps to solve:

-4z + 4 + 12z = 3z + 4 + 5z

~Combine like terms

8z + 4 = 8z + 4

~Subtract 4 to both sides

8z = 8z

~Divide 8 to both sides

0 = 0

All real numbers are solutions.

Set builder notation: {x | R}

This is an identity since every value can be a solution to the equation.

Best of Luck!

Find 40% of 68 please
quester [9]
To find 40% of 68 
you simply divide 40% by 100 and multiply by 68

40/100 x 68 = 32.64

32.64 is 40% of 68.

The same steps can be used to find any percentage of any number.
simply divide the percentage given by 100 and multiply by the total number.
