To solve for x in the equation 3(x-1)=2(1-y), we can first distribute the 3 and 2 to get:3x - 3 = 2 - 2yThen, we can add 3 to both sides and simplify to isolate the term with x:3x = 5 - 2yFinally, we can divide both sides by 3 to solve for x:x = (5 - 2y) / 3To solve for x in the equation 4(x+2)=3(x-1), we can first distribute the 4 and 3 to get:4x + 8 = 3x - 3Next, we can simplify by subtracting 3x and 8 from both sides to isolate the term with x:x = -11To evaluate the expressions 3x+2 and 3x-5 when x = 5, we can substitute 5 for x and simplify:3x+2 = 3(5) + 2 = 17

3x-5 = 3(5) - 5 = 10To solve for y in the equation (1/5)x-3 = (2/5)x+1, we can first add 3 to both sides to isolate the term with x:(1/5)x = (2/5)x + 4Next, we can subtract (2/5)x from both sides to isolate the term without x:(1/5)x - (2/5)x = 4Simplifying the left-hand side gives:-(1/5)x = 4Finally, we can multiply both sides by -5 to solve for x:x = -20To solve for x in the equation 12x+3,61=2, we can first subtract 3,61 from both sides to isolate the term with x:12x = -1,61Finally, we can divide both sides by 12 to solve for x:x = -1,61/12To solve for x in the equation 13x+6,3=42, we can first subtract 6,3 from both sides to isolate the term with x:13x = 35,7Finally, we can divide both sides by 13 to solve for x:x = 2,75
