Equation, an identity, or a contradiction.

7v+42=11 (3v+8) - 2 (13v-1)

48

Step-by-step explanation:

7x+42=11 (3x+8) - 2 (13x-1)

Step 1: Simplify both sides of the equation.

7x+42=11 (3x+8) - 2 (13x-1)

7x+42 = (11) (3x) + (11) (8) + (-2) (13x) + (-2) (-1) (Distribute)

7x+42=33x+88+-26x+2

7x+42 = (33x+-26x) + (88+2) (Combine Like Terms)

7x+42=7x+90

7x+42=7x+90

Step 2: Subtract 7x from both sides.

7x+42-7x=7x+90-7x

42=90

Step 3: Subtract 42 from both sides.

42-42=90-42

0=48

Answer: contradiction

Step-by-step explanation:

7v+42=11 (3v+8) - 2 (13v-1)

Open the bracket

7v+42=33v+88-26v+2

7v+42=33v-26v+88+2

7v+42=7v+90

Collect like term

7v-7v=90-42

0=48

This shows that

7v+42=7v+90 contradict
