Solve the equation for the variable given.

6+^y/₇=11

• 119

• 135

• 35

• 19

Select the equation for:

Five more than a number is negative three.

• x + 5 = -3

• 5x = 3

• 5 - x = -3

• 5 divided by x is 3

5x - 4 + 2x = 3

• x = 1

• x = 2

• x = 3

• x = 4

-11 + 3(b + 5) = 7

• b = 1

• b = -1

• b = 3

• b = -3

Solve:
3(3x - 6) = 18

• x = 4
• x = -4
• no solution
• infinite solutions

2x + 3(5x - 7) = 47

• 1
• 2
• 3
• 4
