Equations and Inequalities

Solve:

 $2x-5=3x+4$  

 

Enter only the value of x, not "x = (a)   ".  No spaces.

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

Jasmine solve the following equation using the steps shown:
Step 1:  $6x+9=3x-3$  

Step 2:   $3x+9=-3$  

Step 3:   $3x=-12$  

Step 4:   $x=-4$  

What operation did she perform to get from Step 1 to Step 2? 

• Subtract 3x from both sides

• Divide both sides by 3

• Subtract 9 from both sides

• Divide both sides by 2

 $12h-7=6h+8$  

•  $x=7$  

•  $x=\frac{1}{6}$  

•  $x=2\ \frac{1}{2}$  

•  $x=\frac{2}{5}$  

 $6x=2\left(7x+3\right)$  

•  $x=-\frac{3}{4}$  

•  $x=-1\ \frac{1}{3}$  

•  $x=-\frac{3}{2}$  

•  $x=1$
