Solve the equation 5x + 3(x − 1) = 8(x + 2) – 10

Solve the equation 18x-2(7x + 3) = -38

Solve the equation |2x + 5| = 9

Solve the equation 11-(3x + 1) = 7(x − 6) + 2

Solve the equation -2|x − 4 |+7 = -3

Solve the equation y = 7x - 3w for x

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

What do we call the number that is being multiplied by a variable?

• Variable
• Term
• Expression
• Coefficient

Is there a mistake on the equation solved? If so where was the mistake made?

• This equation is solved correctly.

• The mistake was made on the first step of combining like terms on the left side.

• The mistake was made on the second step of moving the variable to the left side.

• The mistake was made on the third step of moving the constant to the right side.

• The mistake was made on the last step when isolating the variable by removing the coefficient

You need to combine like terms when you see more than two terms per side of an equation.

Example: 3x + 5 - 2x = 6x + 3

• True

• False
