Which is a correct first step for solving this equation? 4x=7+3(2x−5)

Step-by-step explanation:

The easiest first step is to remove the brackets. Other things could be done, but they are done just because you can.

4x = 7 + 3*2x - 5*3        Just to show you more, I'll keep going.

4x = 7 + 6x - 15              Combine the minus 15 and 7

4x = 6x + 7 - 15

4x = 6x - 8                     Now add 8 to both sides. It's a toss up of what to do

4x + 8 = 6x - 8 + 8

4x + 8 = 6x                    Subtract 5x from both sides

4x - 4x + 8 = 6x - 4x

8 = 2x                             Divide by 2

x = 4

The steps usually follow this order.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
