Question

look at step by step solution shown below and fill in the missing stepthe solution is the missing step

Answer 1

Solving an Equation

We are given the equation:

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

The first step is to multiply the constants by the binomials in parentheses:

`6x+15=20-4x`

This step was correctly done by Jose.

The second step is to 'pass' the 4x from the right side of the equation to the left by adding 4x on both sides:

`10x+15=20`

This step was also correct.

Now we must 'pass' 15 to the right by subtracting 15:

`10x=5`

And here we find the first error. Jose subtracted 15-20 instead of 20-15 and erroneously got -5.

Answer: First error in step 3
