Cooperate and exchange, explore new knowledge

1. How is this equation different from the equation learned in the previous class (3x+0.5x=10)?

2. How can we change it into the same form as the equation learned in the previous class? What is the basis for deformation?

3. What did you find when you solved the equation? What is this method of solving equations?

Changing the sign of a term on one side of an equation and moving it to the other side of the equal sign is called moving a term.

3x+20=4x-25

Venus' fiery eye: judge right or wrong.

(1) From 5x=4x+8, move the terms to get 5x–4x=8,

(2) From 3x = 8- 2x, transfer the terms to get 3x +2x = -8

(3) From 7+x=13, transfer the terms to get x =-13+7

(4) From 6 + x = 8, move the terms to get x = - 8- 6

fill in the blank

Transform the equation by placing the terms containing the unknowns on one side of the equation and the constant terms on the other side of the equation.

(1), 2x -3 = 6 is deformed into 2 x = 6____

(2), 5x = 3x -1 is deformed into 5 x __= -1

(3), 2.4y +2 = -2+2y is deformed into 2.4 y ____= -2____
