There are two approaches to solving the equation -3x + 10 = 4x - 20 Subtract 4x from both sides. OR Add 3x to both sides.

–7x + 10 = –20 OR 10 = 7x – 20

Solve the equation using both approaches.

What is the solution?

a. x = -30/7
b. x = -7/30
c. x = 30/7
d. x = 7/30

You and a friend race across a field to a fence and back. your friend has a 50-meter head start. the equations shown represent you and your friend's distances dd (in meters) from the fence tt seconds after the race begins. find the time at which you catch up to your friend. you: d=∣−5t+100∣d=∣−5t+100∣ your friend: d=∣−313t+50∣∣

One x-intercept for a parabola is at the point (-0.33,0). use the quadratic formula to find the other x-intercept for the parabola defined by the equation y=-3x^2+5x+2
