Solving and Analyzing One Variable Equations and Inequalities

solve for x in the equation: 3x-5(7)=(4x)(3)

• -35/9

• 35/9

• 35/4

• -35/4

Solve for x: (3x)(5+2)=47(4)

solve for x: 3(x+4)=24(x-3)

5x+37(2)= 3x-89(2)

analyze the equation: 3x+6=7(6-4). Without solving the equation, what will x be equal to?

• (42-4-6)/3

• (7(6-4)-6)/3

• (3(6-4)-6)/7

• (7(6-4)+6)/3

Looking at the equation 3x + 10 = 16, what can be done to get x alone?

• -16 on both sides of the equal sign

• -10 on both sides of the equal sign

• -3 on both sides of the equal sign

• divide by 3 on both sides of the equal sign (but not all terms)

• x= 10
• x= -10
• x= 9
• x= -9

Answer explanation

1) Distribute

2) Add/Subtract constants
