24) Solve for x -3x + 4 = -8 A) B) x=4 X=-4 No Solution D) *--

Answer 1

I'll teach you how to solve -3x + 4 = -8

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

-3x + 4 = -8

Subtract both sides by 4:

-3x+4-4 = -8-4

Simplify:

-3x=-12

Divide both sides by -3:

-3x/3 = -12/3

Simplify:

-3x/3= x

-12/3= 4

x=4

Your Answer Is x=4

Answer 2

Answer:

x=4

Step-by-step explanation:

In equations, its important to keep both sides of the equation balanced because if you complete an operation on one side of the equation only then the whole equation will change and your solution will end up wrong so that's an important rule to remember when solving equations so,

→ - 3x + 4 = - 8

⇒ Minus 4 from both sides to isolate -3x

→ - 3x = -12

⇒ Divide both sides by -3 to isolate x

→ x = 4

⇆ We can substitute x = 4 back into the equation to verify our solution, if we get -8 on both sides then we can confirm that our solution is correct

→ - 3x + 4 = -8

⇒ Substitute x = 4 back in

→ -3 × 4 + 4 = -8

⇒ Simplify

→ -12 + 4 = -8

⇒ Simplify further

-8 = -8

So we have confirmed that x = 4 is the correct solution to this equation
