Two-step Equations

Where/what is the mistake?

• Line 2 - You should add 12 to both sides.
• Line 4 - You should multiply both sides by the reciprocal.
• Line 4 - You should multiply both sides by the original fraction. 
• Line 5 - There was a calculation error.

• q = $-\frac{2}{35}$

• q = $\frac{2}{35}$

• q = -4.63

• q = 4.63

• d = $\frac{10}{7}$

• $d\ =-\frac{10}{7}$

• $d\ =\ -1\frac{3}{7}$

• d = $\ 1\frac{3}{7}$

• x = -3.5

• x = 3.5

• x = 4.6

• x = - 4.6

• v = 9.4

• v = -9.4

• v = 16.5

• v = -16.5

4x + 7 = 23

• x = 16
• x = 4
• x = 9
