Solving linear equations

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

Solve:
7x + 19 = -2x + 55

• 4
• 14.8
• 8.2
• -4

Solve for x:
2(3x + 4) + 2 = 4 + 3x

• 2
• -2/3
• 10
• -2

Solve:
2(2x + 3) = -6(x + 9)

• 1.2
• 6
• -6
• 7.5

• 2
• 1
• -1
• -2

Which is the correct first step in solving the equation shown?

• Subtract 33 from both sides

• Add 33 from both sides

• Add 3.5 from both sides

• Multiply both sides by -3.5

In solving the equation 2x-5=27, what step to do first?

• divide 2 on both sides of the equation

• add 5 on both sides of the equation

• multiply 2 on both sides of the equation

• subtract 5 on both sides of the equation

Solve:

2(2x + 3) = -6(x + 9)

• $x=1.2$

• $x=6$

• $x=-6$

• $x=7.5$

 $\frac{5x}{7}-\frac{x}{14}=\frac{9}{7}$  

 $\frac{5}{12}x-\frac{3}{4}=\frac{7}{6}-\frac{2}{9}x$
