Question

combine the like terms.3a+4b-2a+3-7​

Answer 1

Answer:

3a + 4b + -2a + -3b = 0

Reorder the terms:

3a + -2a + 4b + -3b = 0

Combine like terms: 3a + -2a = 1a

1a + 4b + -3b = 0

Combine like terms: 4b + -3b = 1b

1a + 1b = 0

Solving

1a + 1b = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1b' to each side of the equation.

1a + 1b + -1b = 0 + -1b

Combine like terms: 1b + -1b = 0

1a + 0 = 0 + -1b

1a = 0 + -1b

Remove the zero:

1a = -1b

Divide each side by '1'.

a = -1b

Simplifying

a = -1b
