Front

How do you solve the equation v + 4 = 10?

Back

Subtract 4 from both sides to isolate v: v = 10 - 4, so v = 6.

Front

What is the first step to solve the equation n + 4 = 12?

Back

Subtract 4 from both sides to isolate n: n = 12 - 4, so n = 8.

Front

Translate the phrase '4 more than x equals 7' into an equation.

Back

x + 4 = 7.

Front

How do you solve the equation 234 + N = 389?

Back

Subtract 234 from both sides to isolate N: N = 389 - 234, so N = 155.

Front

What is the solution to the equation x + 4 = 7?

Back

x = 7 - 4, so x = 3.

Front

What operation would you use to solve the equation 10 - v = 4?

Back

Add v to both sides and subtract 4 from both sides: v = 10 - 4, so v = 6.
