Step-by-step explanation:

Step 1: Define Systems

y = 4x + 2

6x + 2y = 8

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                  6x + 2(4x + 2) = 8Factor GCF:                                                                                                       2[3x + (4x + 2)] = 8[Division Property of Equality] Divide 2 on both sides:                                  3x + 4x + 2 = 4Combine like terms [Addition]:                                                                        7x + 2 = 4[Subtraction Property of Equality] Subtract 2 on both sides:                        7x = 2[Division Property of Equality] Divide 7 on both sides:                                  x = 2/7

Step 3: Solve for y

Substitute in x [Original equation]:                                                                  y = 4(2/7) + 2Multiply:                                                                                                             y = 8/7 + 2Add:                                                                                                                   y = 22/7

Step 4: Evaluate

Substitute in variables:                                                                                     2/7 + 22/7Add:                                                                                                                   24/7

The answer to #44 is 10.4444, so g is the answer i divided the time by the miles. 47
