Solving Literal Equations in Algebra 1

What is the first step in solving for x in the slope-intercept form of a linear equation?

• Multiply both sides by m

• Add b to both sides

• Divide both sides by m

• Subtract b from both sides

After isolating mx in the equation y = mx + b, what is the next step to solve for x?

• Divide both sides by m

• Multiply both sides by m

• Subtract y from both sides

• Add y to both sides

In the second example, what operation is performed to isolate y after subtracting ax from both sides?

• Add b to both sides

• Divide both sides by b

• Subtract b from both sides

• Multiply both sides by b

What is the final expression for y in the second example?

• y = c - ax / b

• y = c + ax / b

• y = c + ax * b

• y = c - ax * b

In the third example, what is the reciprocal of h/2?

• 2/h

• h

• h/2

• 1/h

What is the final expression for b in the third example?

• b = 2a/h - c

• b = a/2h + c

• b = 2a/h + c

• b = a/2h - c

In the fourth example, what operation is used to isolate r after dividing by pi?

• Take the square root of both sides

• Square both sides

• Multiply both sides by pi

• Subtract pi from both sides

What is the final expression for r in the fourth example?

• r = pi / sqrt(a)

• r = a / sqrt(pi)

• r = sqrt(a / pi)

• r = sqrt(a * pi)

In the fifth example, what is the first step to isolate y from the denominator?

• Divide both sides by y - c

• Subtract c from both sides

• Multiply both sides by y - c

• Add c to both sides

In the sixth example, what is the final step to isolate r sub 2?

• Subtract r from both sides

• Add r to both sides

• Divide both sides by r sub 1 - r

• Multiply both sides by r sub 1
