Select the value of x that makes the equation

2x + 5 = 9

• x = 1

• x = 2

• x = 3

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = ^(R-c)/_a 

Solve:
y = mx + b , for b

• y - mx = b
• y + mx = b
• ^y/_mx = b
• y + mx = -b

Solve for y:
2x + y = 41

• x = 2y + 41
• y = 2x -41
• y = -2x + 41
• x = y -39

Solve for y:
x + y = 4

• y = x + 4
• y = -x + 4
• x = -y + 4
• x= y - 4

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16
