The goal of solving two-step equations is to:

• francine
• Find the coefficient 
• Find the value of the variable

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations
• math
• variable
• PEMDAS

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Add 7
• Subtract 7

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

Solve for x:
-6x + 1 = -11

• x = 2
• x = 1.2
• x = 12
• x = -2

33 = 4a - 7

• a=-10
• a=10
• a=4.5

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

26 = 5a + 1

• a= 5 ⁴∕₅
• a= no solution
• a= 0
• a= 5
