What is the first step to solve this equation: x - 5 = 7 - 2x?

Back

Add 2x to both sides of the equation to combine like terms.

Front

Which operation will you use to solve a = b + c for c?

Back

Subtract b from both sides of the equation to isolate c.

Front

Rewrite the equation 6x - 2y = 10 in slope-intercept form.

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The equation can be rewritten as y = 3x - 5.
