please solve it step by step​

Answer 1

Answer:

2a + 3b + 4

Step-by-step explanation:

Subtract the numbers

5 - 2a + 3b + 4a - 1

4 - 2a + 3b + 4a

Combine like terms

4 - 2a + 3b + 4a

4 + 2a + 3b

Rearrange terms

4 + 2a + 3b

2a + 3b + 4

Solution = 2a + 3b + 4

Answer 2

$\sf \bf \: Question \: –$

Simplify each of the following expressions and find their values if x = 2, a = -1, and b = 3.

• 5 - 2a + 3b + 4a - 1

-------------------

Given :

• 5 - 2a + 3b + 4a - 1
• x = 2
• a = -1
• b = 3

To find :

• their values

Solution :

⇒Let's simplify the expression, first.

→ 5 - 2a + 3b + 4a - 1 (5 - 1 = 4)

→ 4 - 2a + 3b + 4a (-2 + 4 = 2)

→ 4 - 2a + 3b

Now, since we have simplified the expression we can now find the value of the expression.

→ 4 - 2a + 3b

→ 4 - (2 × -1) + (3 × 3)

→ 4 - (-2) + 9

→ 6 + 9

→ 15

• Therefore, the value of 5 - 2a + 3b + 4a - 1 is 15.
