Question

if 8a-7=5a+3 find 'a'​

Answer 1

Answer:

a = -3.333333333

Step-by-step explanation:

Simplifying

8a + 7 + -5a + 3 = 0

Reorder the terms:

7 + 3 + 8a + -5a = 0

Combine like terms: 7 + 3 = 10

10 + 8a + -5a = 0

Combine like terms: 8a + -5a = 3a

10 + 3a = 0

Solving

10 + 3a = 0

Solving for variable 'a'.

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

Add '-10' to each side of the equation.

10 + -10 + 3a = 0 + -10

Combine like terms: 10 + -10 = 0

0 + 3a = 0 + -10

3a = 0 + -10

Combine like terms: 0 + -10 = -10

3a = -10

Divide each side by '3'.

a = -3.333333333

Simplifying

a = -3.333333333
