\sf 3a-(-1) = -5

Question

`\sf 3a-(-1) = -5`

Answer 1

Explanation:

Ok:

1. First solve the equation on the left!!
3a-(-1)= 3a+1=-5

2. Make 3a the only variable on the left side of the equal sign. Move the +1 over the equal sign. Remember that if a number flips over the equal it becomes opposite!

3a=-5-1=

3a=-6

3*a=-6

a=-6/3

a=-2

3. Always double check!

3*-2+1=-5

True!

Answer: a=-2

Answer 2

a = -2

Explanation:

The given equation is,

→ 3a-(-1) = -5

Now the value of a will be,

→ 3a-(-1) = -5

→ 3a + 1 = -5

→ 3a = -5 - 1

→ a = -6/3

→ [ a = -2 ]

Hence, the value of a is -2.
