Answer:

a. 4a−8b+4c+70

b. x=2

Step-by-step explanation:

[tex]a. \: (7a−5b+4c)−(3a+3b−70)[/tex]

[tex]7a−5b+4c−(3a)−(3b)−(−70)[/tex]

[tex]7a−5b+4c−3a−3b+70[/tex]

[tex]4a−5b+4c−3b+70[/tex]

[tex]4a−8b+4c+70[/tex]

b. Let's solve your equation step-by-step.

5x+1=2x+7

Step 1: Subtract 2x from both sides.

5x+1−2x=2x+7−2x

3x+1=7

Step 2: Subtract 1 from both sides.

3x+1−1=7−1

3x=6

Step 3: Divide both sides by 3.

[tex] \frac{3x}{3} = \frac{6}{3} [/tex]

x=2
