7 times the sum of a number and 4 is the same as 8 decreased by 3 times a number

7(x4) = 8-x

x= -2

your first step would be to move your 3x to the other side of the equation by adding 3x to both sides after this your equation should look as follows: 7(4+x)+3x=8 2nd: you should distribute your 7 to the numbers inside of the parentheses and combine like terms to get 10x+28=8 then you move your 28 to the other side by subtracting 28 and you will get 10x=-20 divide by ten to get the answer which is x=-2

Edit: Sorry for the answer before. I realised my mistake.
