Answer:

1. ) d+17=28

Step 1: Subtract 17 from both sides.

d+17−17=28−17

d=11 (answer)

2.) Let's solve your equation step-by-step.

−30=15+c

Step 1: Simplify both sides of the equation.

−30=c+15

Step 2: Flip the equation.

c+15=−30

Step 3: Subtract 15 from both sides.

c+15−15=−30−15

c=−45 (answer)

3.) Let's solve your equation step-by-step.

3f=−12

Step 1: Divide both sides by 3.

3f/3 = -12/3

f=−4 (answer)

4.) Let's solve your equation step-by-step.

−13=5g+32

Step 1: Flip the equation.

5g+32=−13

Step 2: Subtract 32 from both sides.

5g+32−32=−13−32

5g=−45

Step 3: Divide both sides by 5.

5g/5 = 45/5

g= -9 (answer)

5.) Let's solve your equation step-by-step.

3k+7=34

Step 1: Subtract 7 from both sides.

3k+7−7=34−7

3k=27

Step 2: Divide both sides by 3.

3k/3 = 27/3

k = 9 (answer)
