Front

How do you solve the equation n + 4.7 = -4.7?

Back

Subtract 4.7 from both sides: n = -4.7 - 4.7, which simplifies to n = -9.4.

Front

What is the solution to the equation x - 32.9 = 55.8?

Back

Add 32.9 to both sides: x = 55.8 + 32.9, which simplifies to x = 88.7.

Front

How do you solve the equation x = 128.5 + 224.3?

Back

Add the numbers on the right side: x = 352.8.

Front

What is the solution to the equation 0.2x = 1246?

Back

Divide both sides by 0.2: x = 1246 / 0.2, which simplifies to x = 6230.

Front

How do you solve the equation 7.1 = k ÷ 2?

Back

Multiply both sides by 2: k = 7.1 * 2, which simplifies to k = 14.2.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side by itself, making it easier to solve.

Front
