Step-by-step explanation:
1- 3x-3= 6 (x-10) organise the terms
2- 3x-3= 6x- 60 calculate (always brackets first)
2- 3x-6x= 3-60 Put the like terms on the correct side. Always put terms with x on the left.
3- -3x= -57 Calculate sums
4- x= -57÷-3=19 Divide
5- x= 19
22 is the answer to this math problem
75 degrees because 42+63=105
180-105=x
<em>Absolute value represents distance from zero on a number line.</em>
<em>-7 and 7 are the same distance away from zero, 7 units.</em>
