1. Solve |2 - 3x| = 7.

A. {-15, 3}

B. {-3, 15}

C. {-3, 5/3}

D. {-5/3, 3}

Solve the equation for y: 4x + 3y = - 12.

A. y = - 4 + 4x

B. y = - 4 - 4/3 x

C. y = - 12 + 4x

D. y = - 12 - 4/3 x

Solve the equation for m: A = 2 (m - w).

A. m = (A + w) / 2

B. m = 2 (A + w)

C. m = A + w/2

D. m = A/2 + w

1.

for |a|=b assume a=b and a=-b

|2-3x|=7 solve

2-3x=7 and 2-3x=-7

minus 2 both sides

-3x=5 and - 3x=-9

divide both sides by - 3

x=-5/3 and x=3

D

2. minus 4x both sides and divide by 3

y=-4/3x-4

B

3.

divide both sides by 2 and add w to both sides

A/2+w=m

D

1. D

2. B

3. D

distribute, add 2w to both sides and divide by 2
