Ok so the formula is 4x + 7 = 19
first things first, let's get the x alone by subtracting the 7 over to the right side
4x = 12
now divide each side of the equation by 4
x = 3
And there is your answer!! :)
She should have added 2 to both sides of the equation instead of subtracting 2.
2x -2 = 14
Add 2 to both sides:
2x = 16
Divide both sides by 2:
x = 8

Step-by-step explanation:
5 x 4.5 = 22.5 (km)
150 – 22.5 = 127.5 (km)
35 – 5 = 30 (km/h)
127.5/30 = 4.25 (h)
4.25 x 35 = 148.75 (km)
Alternatively,
Let x be the distance that he cycles.
x/35 + (150 – x)/5 = 4.5
x + 1050 – 7x = 157.5
6x = 892.5
x = 148.75
Ans : 148.75km.
