Question

An equation is shown below:

4(2x - 5) + 15 = 11

Write the steps you will use to solve the equation and explain each step

Answer 1

first distribute the 4 to the 2x and the -5

Answer 2

first of all you can subtract 15 from both sides to get the constants on one side

4(2x-5)+15 -15=11-15
4(2x-5)=-4

now you would divide by the scale factor, in this case 4
so divide by 4 on both sides so you can get the expression on its own
then rearrange to get x

Answer 3

so x =2 ??

Answer 4

the way i did it i just distributed the 4 and got
8x -20 + 15 = 11 then you add 15 to -20
8x - 5 = 11 then you add 5 to both sides
8x = 16 then you can divide by 8
x = 2

Answer 5

so yes you're right :)
