Question

Use the drop-down menus to complete each equation so the statement about its solution is true. 5−4+7x+1

Answer 1

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Explanation:

Simplifying

5 + -4 + 7x + 1 = 7x + 1

Reorder the terms:

5 + -4 + 1 + 7x = 7x + 1

Combine like terms: 5 + -4 = 1

1 + 1 + 7x = 7x + 1

Combine like terms: 1 + 1 = 2

2 + 7x = 7x + 1

Reorder the terms:

2 + 7x = 1 + 7x

Add '-7x' to each side of the equation.

2 + 7x + -7x = 1 + 7x + -7x

Combine like terms: 7x + -7x = 0

2 + 0 = 1 + 7x + -7x

2 = 1 + 7x + -7x

Combine like terms: 7x + -7x = 0

2 = 1 + 0

2 = 1

Solving

2 = 1
