Best ResponseYou've already chosen the best response.0The work of a student to solve the equation 2(3x − 4) = 8 + 2x + 4 is shown below: Step 1: 2(3x − 4) = 8 + 2x + 4 Step 2: 5x − 6 = 12 + 2x Step 3: 5x − 2x = 12 + 6 Step 4: 3x = 18 Step 5: x = 6 In which step did the student first make an error and what is the correct step? Step 2; 6x − 6 = 2(6 + x + 2) Step 2; 6x − 8 = 12 + 2x Step 3; 5x − 2x = 12 − 6 Step 3; 5x + 2x = 12 + 6

Best ResponseYou've already chosen the best response.1Both equations equal y so this means we can combine them together. Line C: y = x + 14 Line D: y = 3x + 2 Will become: x+14 = 3x+2 Then you'd subtract both sides by 3x: (x+14−3x=3x+2−3x−2x+14=2) Next subtract by 14 on both sides: (−2x+14−14=2−14−2x=−12) After that you'd divide both sides by 2: −2x/−2=−12/−2 x = 6 So now we have x all you have to do now is calculate for y and to do that put the value of x (6) in the equations: y = 6 + 14 (20) y = 3*6 + 2 (20) y = 20 The solution is (6,20) Your answer would be A.

Best ResponseYou've already chosen the best response.0Peter is 2 years older than Winnie. Peter's age is 16 years less than seven times Winnie's age. The equations below model the relationship between Peter's age (p) and Winnie's age (w): p = w + 2 p = 7w − 16 Which is a possible correct method to find Peter's and Winnie's ages? Solve w + 2 = 7w − 16 to find the value of w. Solve p + 2 = 7p − 16 to find the value of p. Write the points where the graphs of the equations intersect the x axis. Write the points where the graphs of the equations intersect the y axis.
