step 1, move -5 on the left side to the right side and change the sign then add up with 55
step 2, multiply 20 by (10 - 13x) by the associative property
step 3, add the coefficient of the variable x on the left side and move 20 to the right side by changing its sign
step 4, move -34x to the left side by changing the sign then add up with -17x
step 5, to find the x value, move the x coefficient to the right side and divide it, you get the value
