Evaluate this expression (3+4)-4/42+3(4+2)/3​

Step-by-step explanation:

Use PEDMAS

(3 + 4) - 4/42 + 3(4 +2)/3 = 7 - + 3 *      {Inside parenthesis}

                                        = 7 - + 6     {Division}

                                        = 13 -

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
