Question

Grant attempted to solve an equation but made an error. What is his error, and which step did he make it in?

Answer 1

Answer:

Step-by-step explanation:The error is in step 2. −x and 3x combine to make 2x, not 4x. i just did this question so sorry i answered late

Answer 2

Answer:

B. The error is in step 2, $-x\text{ and }3x$ combine to make $2x$ not $4x$.

Step-by-step explanation:

We have been an image that represents Grant's solution of an equation. We are asked to find Grant's error.

$-4+2x=5-(x-3)+3x$

Let us see our given equation by using distributive property $a(b+c)=a\cdot b+a\cdot c$.

$-4+2x=5-x+3+3x$

Now we will gather like terms.

$-4+2x=5+3+3x-x$

$-4+2x=8+2x$

Upon looking at Grant's work, we can see that he combined $3x-x$ incorrectly. Instead of subtracting x, he added x to 3x, therefore, Grant made an error in step 2 and option B is the correct choice.
