Solve each equation. Check your solution. 3g + 5 = 17

Answer explanation

To solve the equation 3g + 5 = 17, subtract 5 from both sides to isolate 3g. Then divide both sides by 3 to find the value of g. Finally, check the solution by substituting it back into the original equation.

Solve each equation. Check your solution. 9 = 4a + 13

Answer explanation

To solve the equation 9 = 4a + 13, subtract 13 from both sides to get -4 = 4a. Divide both sides by 4 to find a = -1. The solution is a = -1.

Solve each equation. Check your solution. 13 = 5m – 2

Answer explanation

To solve the equation, add 2 to both sides. Then divide both sides by 5. The solution is m = 3. Check by substituting 3 for m in the equation.

Solve each equation. Check your solution. –15 = 2t – 11

Solve each equation. Check your solution. 7k – 5 = –19

Answer explanation

To solve the equation 7k - 5 = -19, add 5 to both sides to isolate 7k. Then divide both sides by 7 to find k. The solution is k = -2. Check by substituting -2 for k in the original equation.

Solve each equation. Check your solution. 13 = 4x –11

Answer explanation

To solve the equation 13 = 4x - 11, add 11 to both sides to isolate 4x. Then divide both sides by 4 to find the value of x. Check your solution by substituting it back into the original equation.
