how do you solve this i've tried many ways and i always get stuck.
-4(2x - 3 ) = -8x + 5
you use -4x times 2x first, then you times -3. so you have (-8+12)=8x+5. you know -8+12 is 4, so the equation becomes 4=8x+5. so x is probably a negative number. so 4=5+8x and then you know 4-5=8x. -1=8x, so x is -1/8. i think that's the answer.
opps. i think i missed the x. is there even an answer?
-4*2x=-8x
-4*-3=-12 so
-8x-12=-8x+5
Adding 8x to each side gives
-8x+8x-12=-8x+8x+5
0x-12=0x+5
So the x term cancels and this equation has no solution.Obviously -12 does not equal +5.
I hope this helps.
Oy! 2 mistakes in the responses(It's ok...we all make mistakes) Ultimately, there is no answer. BUT...
-4 (2x-3) = -8x +5
-8x + 12 = -8x +5
The 8x's cancel each other out. So Dr. Bob's response should say
"Obviously +12 does not equal +5"
Bob's right: There's no solution.
durrrr
To solve the equation -4(2x - 3) = -8x + 5, we can follow these steps:
1. Distribute the -4 to the terms inside the parentheses:
-4 * 2x + (-4) * (-3) = -8x + 5
This simplifies to:
-8x + 12 = -8x + 5
2. Next, we want to gather like terms on the same side of the equation. In this case, we can subtract -8x from both sides:
-8x - 8x + 12 = -8x - 8x + 5
Simplifying this expression, we get:
0x + 12 = 0x + 5
3. Since we have 0x on both sides, it cancels out and we're left with:
12 = 5
4. This is a contradiction since 12 does not equal 5. Therefore, there is no solution to this equation.
So, the answer is that there is no solution to the equation -4(2x - 3) = -8x + 5.
