Solve for x in the following equation 3 + x = 8

Step 1: Since the 3 is positive in this equation, to bring it to the other side we would do the opposite of what it shows meaning we would subtract it from 8 giving us the answer 5. The new equation would be x = 5, giving us the answer for x.

Solve 200 divided by 5.

Step 1: See how many times 5 goes into each number of 200. 5 does not go into 2 evenly so we figure out how many times 5 goes into 20 which would be 4. Bring the 4 to the top of the problem. Step 2: Multiply 5 by 4 and put that number under the 20 and subtract, giving you 0. Step 3: Bring down the second 0 in 200 making the number 00. 5 goes into 0 zero times so the 0 would be brought to the top, making the answer 40.

Solve for x in the following equation 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13

Step 1: Multiply numbers outside the parenthesis by each of the numbers inside the parenthesis making the new equation -15x - 10 - 2x + 3 = -16x - 20 + 15 Step 2: Add like terms. New equation is -17x - 7 = -16x - 5 Step 3: Add 16x to one side and add 7 to the other making the new equation -1x = 2 Step 4: Solve for x by diving 2 by -1. x = -2
